Not that I am very knowledgeable about things like chemistry but there is a website that has all the info you want on converting drugs and how to make drugs but, be advised there are laws that make it illegal to make these controlled drugs. Violating these laws can present you with large fines and imprisonment for violating them so do so at your own risk. From what I can see you really should have a graduate degree in chemistry to be messing around with these chemicals. There are many procedures out there for the production of N-methyl-amphetamines methamphetamines from various starting materials, such as phenylpropanone P2P or ephedrine, but what if you already have an amphetamine or phenethylamine and wanted to add a methyl group to the nitrogen atom? If you would use the first reaction that comes to mind for the conversion, to alkylate the amphetamine with methyl iodide or dimethylsulfate, you would be disappointed, as you would get a mixture of products, most important the N,N-dimethyl-amphetamine of very low activity , as once the amphetamine has been methylated to methamphetamine, the molecule is much more succeptible to another alkylation, and thus the dimethyl- amphetamine is formed much faster than the remaining amphetamine is alkylated to methamphetamine. Actually, in the reaction mix you would find unreacted amphetamine, N-methylamphetamine, N,N-dimethyl- amphetamine and even some of a quaternary N,N,N-trimethylamphetammonium salt. To avoid this happening, we must usually resort to indirect methods of introducing the methyl group. Amphetamine can also from an amide with formic acid, N-formylamphetamine, if boiled in a Dean-Stark apparatus where the formed water in the reaction is continously removed, thus driving the formation of the amide forward. The amide can then be reduced by for example lithium aluminum hydride. Another way is to react the amine with benzaldehyde to form an imine, which then can safely be alkylated with methyl iodide or dimethyl sulfate, and after hydrolysis of the resulting compound, N-Methylamphetamine is formed. Finally, it must be said that using exotic reagents like cesium salts, it might be possible to directly mono-methylate amphetamine without too much overalkylating taking place. You get an approximate 9: The selectivity might be somewhat lower with methylations than with the butylation described in the last synthesis of this document. N-Methyl-amphetamines were prepared by the reaction of the corresponding amphetamine with formaldehyde and reduction in the absence of acid. Similarly, 70g d -amphetamine in alcohol with aluminum and 1 mole formaldehyde gave d -methamphetamine, which was converted to the phosphate salt. This procedure is for the methylation of 2-phenethylamine, but it can easily be adapted for use with any amphetamine. A solution of Additional ethanol ml , 15 g. When hydrogen absorption was complete, the catalyst was removed, and the filtrate and washings concentrated to dryness. A solution of 6. Removal of the solvent gave an 8. The solvent was removed under vacuum giving 7. An alternate process for the synthesis of this amide involved holding at reflux for 16 h a solution of 10g of MDA as the free base in 20 mL fresh ethyl formate. Removal of the volatiles yielded an oil that set up to white crystals, weighing 7. A solution of 7. The reaction mixture was held at reflux for 4 days. After being brought to room temperature, the excess hydride was destroyed with 7. O in an equal volume of THF, followed by 7. The solids were removed by filtration, and the filter cake washed with additional THF. The combined filtrate and washes were stripped of solvent under vacuum, and the residue dissolved in mL CH. Extraction with 3x75 mL CH. There was obtained 6. O to produce a lasting turbidity. On continued stirring, there was the deposition of fine white crystals of 3,4-methylenedioxy-N-methylamphetamine hydrochloride MDMA which were removed by filtration, washed with Et. A mildly exothermic reaction began at once. The mixt was heated under reflux until no more H2O was present in the condensate ca. The 2-phase mixt was heated for 90 min on the steam bath, cooled slightly, treated with ml of H. O, and heated for an addn 20 min. After cooling in ice, the aqueous layer was washed twice with Et. Selective N-alkylation of primary amines was developed using cesium hydroxide to prepare various secondary amines efficiently. A cesium base not only promoted monoalkylations of primary amines but also suppressed overalkylations. Various amines and alkyl bromides were examined, and the preliminary results demonstrated this methodology was highly chemoselective, favoring mono-N-alkylation over dialkylation. In particular, use of amino acid derivatives afforded the desired secondary amines exclusively. Among the cesium bases examined, cesium hydroxide monohydrate, in general, gave the highest yields and selectivities although cesium carbonate also worked well, depending on substrates. To confirm the possible cesium effect, defined by the enhanced reactivities in the presence of cesium salts, comparative studies between cesium bases and other bases were performed, demonstrating that cesium hydroxide was superior to other alkali bases tried with the regard to the observed chemoselectivities. Other alkali hydroxides produced moderate yields of the desired product along with a considerable amount of the tertiary amine, whereas cesium hydroxide allowed for a greater selectivity of 9: It was apparent that an unprecedented 'cesium effect' in N-alkylation was observed as seen in O-alkylation. Interestingly, the next comparative study implied that the cesium base not only promoted N-alkylation of primary amines, but also inhibited the formation of tertiary amines. Under our cesium base promoted N-alkylation conditions, primary and secondary amines exhibited opposing reactivities, suggesting that the improvement of chemoselectivity would stem mainly from the retarded overalkylation or reversal of normally observed alkylation rates. The reaction was stirred for 20 h, filtered to remove the molecular sieves and undissolved inorganic salts, and rinsed several times with EtOAc. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. So a mixture of the two chems in alcoholic solution would be added to the amphetamine free base in alcohol and refluxed for an hour or two. First, the formaldehyde reacts with the primary amine to form an imine, then the imine is reduced to a secondary amine, in this case now a methyl amine, the formic acid itself is oxidised to plain old carbon dioxide, and can be seen escaping the reaction mixture as tiny bubbles, much like a glass of semi flat lemonade…in fact the rate of carbon dioxide emission is used to regulate the speed of this reaction and can be also used to determine when the reductive formylation is completed. Usually a slight stoichiometric excess is used in regard to the amount of formaldehyde needed to complete a methylation like this, and at least one and a half equivalents of formic acid to ensure a high conversion. Of course doing this does not mean you get a more potent product outright, as firstly, you probably have a racemic mixture of amphetamine, dextro and levo isomers fifty percent of each, and both of them have quite different effects, one being a stronger CNS stimulant, and the other has more peripheral stimulant effects, on the cardiovascular system. Using pseudoephidrine or ephidrine, lithium and anhydrous ammonia are put together, pretty violent reaction, result- Meth base, which is then gassed or titrated to get the final product. Second is the old biker stuff. Quite a bit more complicated. Uses methalyamine instead of needing pseudo. The 3 are boiled with a reflux condenser for several hours. Result- Meth base to gas or titrate. The 2 of these use pseudo or ephedrine as the precurser and the other using the methalyanine. To convert adderal or some classic amphetamine, pretty much not gonna happen. Even so there is tons of detail to each process which is left out. Try this without proper education and you going to fry your ass. I think be easiest get one of the recipes off the internet. So is the shake n snake. Ask New Question Sign In. How does one convert amphetamine to methamphetamine? Monomethylation of Amphetamines Monomethylation of Amphetamines by Rhodium Introduction There are many procedures out there for the production of N-methyl-amphetamines methamphetamines from various starting materials, such as phenylpropanone P2P or ephedrine, but what if you already have an amphetamine or phenethylamine and wanted to add a methyl group to the nitrogen atom? Related Questions More Answers Below Is the reaction of amphetamine with chloromethane a reliable method for synthesising methamphetamine? How would we convert methamphetamine to amphetamine? Is methamphetamine just amphetamine with an added methyl group? Which is the most dangerous methamphetamine, amphetamine or methylphetamine? What role does the methyl group in methamphetamines play in its potency compared to non-methylated amphetamines? Thank you for your feedback! It can easily be done with reductive amination. Alkylating agents can be problematic because secondary amines are more easily alkylated than primary amines. Thus, you end up with a mixture of secondary, tertiary, and quaternary amines. The trick is to do reductive amination. You can easily methylate an amine by reaction with formaldehyde to form an imine. This can be followed by reduction with sodium borohydride, which will yield the desired secondary amine methamphetamine. It is possible to do it all in one pot if you use sodium cyanoborohydride, which is strong enough to reduce the imine, but too weak to reduce the aldehyde. Thus, as the imine forms the cyanoborohydride reduces it. To drive it to the product, you can do the reaction over 4 angstrom molecule sieves zeolites , which will absorb any water formed. Alternatively, it could be done in a dean-stark trap where the water is driven off by heat. Without all the chemistry and major detail. There are 3 basic techniques. Hope this makes sense.
