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.

For the first time we have been able to employ enantiopure 1,2‐aminoalcohols derived from abundant amino acids in C−C bond‐forming hydrogen‐borrowing alkylation reactions. These reactions are facilitated by the use of the aryl ketone Ph*COMe. Racemisation of the amine stereocentre during alkylation can be prevented by the use of sub‐stoichiometric base and protection of the nitrogen with a sterically
