The present invention provides a process for the preparation of 2-(thienyl-2)- and 2-(thienyl-3)-ethylamines of the general formula: ##STR1## in which R.sub.1, which is in the 2-, 3-, 4- or 5-position, is a hydrogen atom, a straight-chained or branched alkyl radical or a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or polysubstituted, or R.sub.1 is an alkoxy radical, a halogen atom or a nitro, carboxyl, cyano or amino group; the aminoethyl chain is in the 2- or 3-position of the thiophene nucleus; R.sub.2 is a hydrogen atom or a straight-chained or branched alkyl radical or a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or poly-substituted; and Ar is a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or poly-substituted.
本发明提供了一种制备通式为:##STR1##其中 R.sub.1 在 2-, 3-, 4- 或 5- 位置,是氢原子、直链或支链烷基基团或杂环或非杂环芳基基团,可选地为单或多取代基,或 R.sub.1 是烷氧基、卤素原子或硝基、羧基、氰基或氨基基团;氨基乙基链位于噻吩核的 2- 或 3- 位置;R.sub.2 是氢原子或直链或支链烷基基团或杂环或非杂环芳基基团,可选地为单或多取代基;Ar 是可选地为单或多取代基的杂环或非杂环芳基基团。
