D-Alanine, methyl ester, hydrochloride Use and Manufacturing

Methods of Manufacturing

General procedure: SOClIn a separate reaction, the intermediate reagent V(E) was prepared by suspending V(D) (100 g, 1.12 mol) in 1 L of MeOH. The mixture was cooled to 0-5 D-alanine (2.5 g, 27.8 mmol) was added to a dry flask.Add anhydrous anaerobic methanol (14 mL), stir at 20 ° C for 10 min, Thionyl chloride (5 mL) was slowly added thereto, and the reaction was stirred for 6 hours.After the reaction was completed, the solvent was evaporated, diluted with diethyl ether and filtered.D-Alanine methyl ester 9 was obtained as a white solid, 3.46 g.
