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.
本发明涉及符合以下通式的新N-取代苯胺:##STR1## 其中R.sub.1代表烷基基团或取代烷基基团,R.sub.2代表氢原子、烷基基团或取代烷基基团,R.sub.3代表氰基、氨基甲酰基、羧基或碳酸烷氧基团,R.sub.4代表氢或卤素原子或烷基或烷氧基团。这些化合物是制备着色材料的有价值中间体,特别是作为合成偶氮染料的偶联化合物。
