N-Acetyl-D-serine methyl ester (1.0 g, 0.0062 mole) was dissolved in benzylamine (6.64 g, 0.062 mole) at 0-5° C. The reaction mixture was heated and stirred at 65° C. for 12 hr. The excess benzylamine was removed by distillation under vacuum at 90° C. to get a thick white solid. To this was added 10 ml of methyl tert-butyl ether and stirred for 2 hr at room temperature. The product was filtered and dried under vacuum to obtain (R)-2-acetamido-N-benzyl-3-hydroxy-propionamide (1.09 g, Yield 75%, HPLC: 92%, Chiral HPLC: 78%).
