Reaction Steps

A mixture of 3 g of D-methionine hydrochloride, 50 ml of propionic acid, 0.48 g of DL-methionine (0.2 mole per mole of D-methionine hydrochloride) and 0.16 ml of benzaldehyde (0.1 mole per mole of D-methionine hydrochloride) was stirred at 100° C. for 2 hours. After the reaction, 0.34 g of 35% hydrochloric acid was added to the mixture, and said mixture was ice-cooled. The crystalline precipitates were collected by filtration, and then washed with acetone. 3.10 g of DL-methionine hydrochloride were thereby obtained.
