Antihypertensive compounds of the formula II ##STR1## wherein D is a piperidino or 1,2,5,6-tetrahydropyridino ring; wherein X is chloro or trifluoromethyl; wherein R.sub.1 is hydrogen or hydroxy when the D ring is piperidino, or nothing when the D ring is 1,2,5,6-tetrahydropyridino; and, wherein the moiety Ar is 2-oxo-1-benzimidazolinyl, phenyl, or phenyl substituted by one or two halo, trifluoromethyl, or alkyl, alkoxy, in which the carbon moieties are of 1 to 3 carbon atoms, inclusive, and halo is chloro, bromo, or fluoro, are produced by reacting 4-[[7-(chloro) or (trifluoromethyl)-4-quinolinyl]-amino]benzoic acid with thionyl chloride or a carbonyl diimidazole and subsequent reaction with the selected substituted piperidine or 1,2,5,6-tetrahydropyridine. The pharmacologically acceptable acid addition salts of II can also be used as antihypertensives.
公式II的抗高血压化合物##STR1##其中D是哌啶或1,2,5,6-四氢吡啶环;其中X是氯或三氟甲基;其中R.sub.1是氢或羟基(当D环为哌啶时),或者为空(当D环为1,2,5,6-四氢吡啶时);其中基团Ar是2-氧代-1-苯并咪唑啉基、苯基或被一个或两个卤、三氟甲基或烷基、烷氧基取代的苯基,其中碳基团为1至3个碳原子,卤素为氯、溴或氟。通过将4-[[7-(氯)或(三氟甲基)-4-喹啉基]-氨基]苯甲酸与氯化硫酰或羰基双咪唑反应,并随后与所选的取代哌啶或1,2,5,6-四氢吡啶反应,可以制备出公式II的药理学可接受的酸盐加合物,也可用作抗高血压药物。
