Reaction Steps

To a mixture of 3-methoxy-4-methyl-D-phenylalanine methyl ester hydrochloride (1.60 g) in a mixed solvent of dichloromethane (7 ml) and water (9 ml) was added potassium carbonate (1.70 g) in small portions under ice cooling. Chloroacetyl chloride (0.66 ml) was added to the mixture at 5° C. or below over 15 minutes and then the total mixture was stirred for 30 minutes. The organic layer was separated, washed with an aqueous sodium chloride solution, dried over magnesium sulfate and the solvent was evaporated under reduced pressure to give (2R)-2-[N-(chloroacetyl)amino]-3-(3-methoxy-4-methylphenyl)propionic acid methyl ester in the form of an oily substance.
