D-Lysergic Acid Methyl Ester Usage And Synthesis
Preparation
synthesis of lysergic acid methyl ester: A suspension is prepared from 5.0 g of isolysergic acid amide in 80 ml of anhydrous methanol; the mixture is cooled to about -50°C and, under agitation, 40 ml of a 13N solution of hydrogen chloride in anhydrous methanol is added thereto. The clear solution is allowed to warm up to room temperature and further stirred overnight. The primary amount of the thus-formed ester hydrochloride is thus crystallized. By cooling in an ice bath and adding ethyl acetate, the crystallization is completed, and the precipitate is vacuum-filtered. Yield: 5.2 g (84% of theory) of lysergic acid methyl ester, hydrochloride.
