The organic extracts were dried Na2SO4 and the solvent evaporated to yield a white solid. Passing this material through a short silica column 4: EtOAc yields the product 0. The solution was stirred at ambient temperature for 18 h. The mixture was shaken, and the layers were separated. The aquous layer was extracted five times with chloroform and the combined organic extracts were dried over Na2SO4 and filtered. To this was added 6 ml of a 1.
