Process for converting alpha-angelica lactone to 5-methyl-N-alkyl-2-pyrrolidone using alkyl amines

摘要

This invention relates to a process for producing 5-methyl-N-alkyl-2-pyrrolidone by a) reacting alpha-angelica lactone with alkyl amines and b) hydrogenating the products of step (a) in the presence of a metal catalyst, which is optionally supported.
