Hydrochloric Acid → (2S,4S)-1-methyl-2-aminocarbonyl-4-mercaptopyrrolidine hydrochloride

Participants

Reaction Steps

(2S,4S)-1-Methyl-2-aminocarbonyl-4-acetylthiopyrrolidine (201 mg) was dissolved in methanol (2.4 ml), and a solution of sodium methoxide (54 mg) in methanol (1.2 ml) was added thereto at room temperature under nitrogen stream, followed by stirring at the same temperature for 5 minutes. To the reaction mixture, conc. hydrochloric acid (240 mg) was added, and the solvent was removed. The residue was dissolved in a mixture of chloroform and methanol (4:1) and dried over magnesium sulfate. Removal of the solvent gave (2S,4S)-1-methyl-2-aminocarbonyl-4-mercaptopyrrolidine hydrochloride.
