It has been found that the novel compounds of the formula
wherein R1 is phenyl substituted with 1 to 3 lower alkoxy groups or 1 to 3 halogens. R2 is hydroxy or lower alkanoyloxy, R3 and R4 are, independently, lower alkyl or, taken together, form a piperidine or pyrrolidine ring and n is 2 to 4, and pharmaceutically acceptable acid addition salts thereof are active as calcium channel blockers and, accordingly, are useful as agents for treating ischemia and as agents for lowering blood pressure. They can be preparated by reacting a compound of the formula
with a compound of the formula
and optionally lower alkoxylating the compound obtained.
发现式中的新型化合物
其中 R1 是被 1 至 3 个低级烷氧基或 1 至 3 个卤素取代的苯基。R2 是羟基或低级烷氧基,R3 和 R4 分别是低级烷基,或共同形成哌啶或吡咯烷环,n 是 2 至 4,其药学上可接受的酸加成盐具有钙通道阻滞剂的活性,因此可用作治疗缺血和降低血压的药物。它们可以通过将式
与式
并对得到的化合物进行低级烷氧基化。
