    摘要: The present invention relates to a novel catalytic hydrogenation of substituted 2-methyl cyanopyridyl derivatives, in particular 3-chloro-5-(trifluoromethyl)pyridin-2-yl]acetonitrile [= Py-CN] to substituted 2-ethylaminopyridine derivatives, in particular2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethanamine[= Py-ethanamine] or salts thereof in the presence of metal catalysts, in particular palladium catalysts.
