The present invention provides a process for the preparation of 2-(thien-2-yl)- and 2-(thien-3-yl)-ethylamine derivatives of the general formula: ##STR1## in which R.sub.1, in the 2-, 3-, 4- or 5-position, is a hydrogen or halogen atom, a nitro, carboxyl, cyano or amino group, a linear or branched alkyl or alkoxy radical or a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or polysubstituted, the aminoethyl chain is in the 2- or 3-position, R.sub.2, R.sub.3 and R.sub.4, which are the same or different, are hydrogen atoms or heterocyclic or non-heterocyclic aromatic radicals, which are optionally mono- or polysubstituted, and Ar is a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or polysubstituted.
本发明提供了一种制备2-(
噻吩-2-基)-和2-(
噻吩-3-基)-乙基胺衍
生物的方法,其一般式为:##STR1## 其中,R.sub.1在2-、3-、4-或5-位置上是氢或卤素原子、硝基、羧基、
氰基或
氨基、线性或支链烷基或烷氧基或杂环或非杂环芳基,可选地是单取代或多取代的,
氨乙基链在2-或3-位置上,R.sub.2、R.sub.3和R.sub.4相同或不同,是氢原子或杂环或非杂环芳基,可选地是单取代或多取代的,Ar是可选地单取代或多取代的杂环或非杂环芳基。
