PROCESS FOR PREPARING ALICYCLIC AMINE DERIVATIVES BY HYDROGENATION OF NITROBENZENE DERIVATIVES

摘要

PURPOSE: A manufacturing method of an aliphatic amine derivative is provided to increase yield of an amine derivative and conversion ratio of nitrobenzene derivative, to reduce generation of byproduct, and to manufacture high purity alicyclic amine derivative. CONSTITUTION: A manufacturing method of an aliphatic amine derivative comprises a step of manufacturing an aliphatic amine derivative represented by chemical formula 2 by hydrogenation of a nitrobenzene derivative represented by chemical formula 1. In chemical formula 1, X is -NO2, -Br, I, -COCH3, -OCH3, -C≡N, or -NH2. In chemical formula 2, R is -H or low alkyl group; X' is -H, -NO2, -Br, I, -COCH3, -OCH3, -C≡N, or -NH-R'; and R' is -H or low alkyl group.
