A solution of Removal of the solvent from the pooled extracts yielded This nitrostyrene has been periodically available commercially from a number of sources. This solution was added slowly to a well-stirred suspension of The two phases were separated, and the ether phase dried by the addition of anhydrous MgSO 4. The drying agent was removed by filtration, and the clear filtrate saturated with a stream of anhydrous HCl gas. The formed crystals of 2,5-dimethoxyamphetamine hydrochloride 2,5-DMA were removed by filtration, washed with anhydrous Et 2 O , and dried to constant weight of The qualitative information on 2,5-DMA is very sparse. A seizure of capsules reported by the drug law enforcement authorities some 20 years ago found that each contained some milligrams of the hydrobromide salt. This is equivalent to milligrams of the hydrochloride salt, and suggests that level may be an effective dosage. An intriguing, but little studied, analogue of 2,5-DMA is the compound with methyls in place of the methoxyls. All three isomers of monomethylamphetamine have also been looked at in man. There is a mystery, at least to me, concerning the commercial production of 2,5-DMA. At regular intervals, there is a public announcement of the production quotas that are requested or allowed by the Drug Enforcement Administration, for drugs that have been placed in Schedules I or II. In the Schedule I category there are usually listed amounts such as a gram of this, and a few grams of that. These are probably for analytical purposes, since there are no medical uses, by definition, for drugs in this Schedule. But there is a staggering quantity of 2,5-DMA requested, regularly. Quantities in the many tens of millions of grams, quantities that vie with medical mainstays such as codeine and morphine. I have heard that this material is used in the photographic industry, but I have no facts. Somewhere I am sure that there is someone who has to keep a lot of very careful books! In the area of psychedelic drugs, the value of 2,5-DMA is mainly in its role as a precursor to the preparation of materials that can come from a direct electrophilic attack on the activated 4-position. However, the study of various direct iodinations and fluoridations that would have the N , N -dimethyl substitution on the amphetamine nitrogen atom, would require the 4-proteo- analogue, and this was made from the above nitrostyrene. A solution of the above nitrostyrene, It has also been prepared by the N , N -dimethylation of 2,5-DMA directly, with formaldehyde and formic acid.

I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore the typographic niceties found in the printed edition. Typically the change is little more than expanding a prefix or setting it in italics. The history page has further details. To do so is to risk legal action which might lead to the tragic ruination of a life. Book II of PiHKAL may be distributed for non-commercial reproduction provided that the introductory information, copyright notice, cautionary notice and ordering information remain attached. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
