Abstract

The present application relates to a process for preparing unsymmetric secondary tert-butylamines which, as well as the tert-butyl radical, also comprise an alkyl, cycloalkyl or benzyl radical. They are prepared by reacting corresponding aldehydes with tert-butylamine and hydrogen in the presence of hydrogenation catalysts (reductive amination) in the liquid phase.
