Abstract

The present invention relates to an improved process for the synthesis of (R)-Lacosamide in which free base of O-methyl-N-benzyl-D-Serinamide is not isolated before acylation. The process avoids the use of column chromatography and chiral resolution for the preparation of different stages of Lacosamide.
