N-METHYL-D-ALANINE Use and Manufacturing
A clean autoclave was charged with 63 g of L-p-toluenesulfonyllactate and 500 ml of a 20percent solution of methylamine in methanol. The autoclave was sealed and incubated at 15-30 ° C until the starting HPLC assay was less than 5percent. The reaction mixture was stirred at 50 ° C in a water bath Concentrate to dryness under reduced pressure, add 200 ml of water and reconcentrate to about 200 ml left, and obtain 22.1 g of RN-methyl-alanine by GC content with a yield of 83.1percent and an ee value of 97percent.
