New aryloxy-alkylamine derivatives of the general formula I ##STR1## in which A signifies a benzene or thiophene ring, R and R.sub.1, independently of one another, each hydrogen, alkyl, halogen, CF.sub.3 or alkoxy, R.sub.2 alkyl, cycloalkyl, alkenyl, alkynyl, alkaryl or saturated or unsaturated aliphatic or aromatic acyl, R.sub.3 and R.sub.4 in each case hydrogen, alkyl, alkenyl, alkynyl or cycloalkyl with, in each case, up to 8 C-atoms, whereby R.sub.3 and R.sub.4 can be the same or different but are not simultaneously hydrogen or R.sub.3 and R.sub.4, together with the nitrogen atom connecting them, form a 5- to 7-membered saturated ring or a saturated heterocyclic ring which can possibly contain an oxygen or nitrogen atom as a further heteroatom in the ring, whereby an additional nitrogen atom can be substituted by an alkyl radical with up to 3 C-atoms, and their acid-addition salts possess interesting pharmaceutical properties and are especially suitable as anti-arrhythmics.
该专利描述了一种新的芳氧基-烷基胺衍生物,其通式为I ##STR1## 其中A表示苯环或噻吩环,R和R.sub.1分别独立地表示氢、烷基、卤素、CF.sub.3或烷氧基,R.sub.2表示烷基、环烷基、烯基、炔基、烷基苯基或饱和或不饱和脂肪族或芳香族酰基,R.sub.3和R.sub.4分别表示氢、烷基、烯基、炔基或环烷基,每种基团中均含有不超过8个碳原子,其中R.sub.3和R.sub.4可以相同,也可以不同,但不能同时为氢,或者R.sub.3和R.sub.4连同连接它们的氮原子形成5-至7-成员饱和环或含氧或氮原子的饱和杂环,其中一个额外的氮原子可以被含有不超过3个碳原子的烷基基团取代,它们的酸加成盐具有有趣的药理特性,特别适用于抗心律失常药物。
