摘要:
The present invention relates to a process for the preparation of levetiracetam and, more particularly, to an improved process for the preparation of levetiracetam characterized by a crystallization-induced dynamic resolution of a diastereoisomeric mixture of an (±)-alpha-ethyl-2-oxo-1-pyrrolidine acetamide derivative.
