The present invention relates to new N-substituted anilines which correspond to the general formula: ##STR1## in which R.sub.1 represents an alkyl radical or substituted alkyl radical, R.sub.2 represents a hydrogen atom, an alkyl radical or substituted alkyl radical, R.sub.3 represents a cyano, carbamoyl, carboxy or carbalkoxy radical and R.sub.4 represents a hydrogen or halogen atom or an alkyl or alkoxy radical. These compounds are valuable intermediates for the preparation of coloring materials, especially as coupling compounds for the synthesis of azo dyes.
