HIGHLY SELECTIVE NOVEL AMIDATION METHOD

摘要

The present invention provides an industrial production method with a short process having a high yield of an aliphatic cyclic carboxamide having carboxyl group, which comprises reacting functional group-selectively using an inexpensive condensing agent without protecting the carboxyl group by esterification, that is, reacting carboxylic acid anhydride obtained by reacting carboxylic acid and tertiary carboxylic acid halide with aliphatic cyclic secondary amine having carboxyl group.
