A cyclic amine compound having a prescribed configuration can be efficiently prepared by reducing an imine derivative in the presence of a sulfonic acid. Specifically, a cyclic amine compound which is substituted with an amino group and a carboxyl group in which both groups are arranged in the trans configuration can be prepared efficiently.
