The invention provides compounds of the formula: ##STR1## wherein each of R.sub.1, R.sub.2 and R.sub.3, which can be the same or different, is hydrogen, chloro, bromo, fluoro, methyl, ethyl, methoxy, amino, hydroxy or nitro; R.sub.4 is hydrogen or alkyl of 1 to 7 carbons atoms; X is ##STR2## (R.sub.5 is hydrogen or hydroxy) and n is 1-4; and their non-toxic pharmaceutically acceptable acid additions salts. These compounds exhibit valuable pharmacological activity and are useful in the treatment of mammals, especially as anti-hypertensive agents. Furthermore, some of the compounds have proved to possess diuretic, .beta.-blocking activity and/or antithrombotic activity. The compounds may be made by a variety of methods and may be incorporated in pharmaceutical compositions also comprising a compatible pharmaceutically acceptable carrier.
本发明提供了以下式的化合物: ##STR1## 其中R.sub.1,R.sub.2和R.sub.3可以相同也可以不同,分别为氢,氯,溴,氟,甲基,乙基,甲氧基,氨基,羟基或硝基;R.sub.4为氢或1至7个碳原子的烷基;X为 ##STR2## (R.sub.5为氢或羟基),n为1-4;以及它们的无毒药学上可接受的酸盐。这些化合物表现出有价值的药理活性,并且在哺乳动物的治疗中非常有用,特别是作为抗高血压药物。此外,其中一些化合物已被证明具有利尿、β-阻滞和/或抗血栓活性。这些化合物可以通过各种方法制备,并可以并入含有兼容的药学上可接受的载体的药物组合物中。
