The present invention is concerned with a process of preparing (R)-lacosamide. The process comprises providing an (R,S)-lacosamide precursor and contacting the same with at least an enzyme in the presence of a solvent. The enzyme either stereoselectively hydrolyzes or acetylates an (R)- or (S)-enantiomer of the (R,S)-lacosamide precursor. The process further comprises where appropriate also concurrently, or successively, employing one or more reagents capable of converting the hydrolysed or acetylated (R)- or (S)-enantiomer to (R)- lacosamide.
