A synthesis of all possible N-alkylated 2-n-butyl-imidazo[4,5]pyridine isomers is described as well as their structural assignment by 1H NMR spectroscopy. One of these derivatives, 2,-n-butyl-3-[2′- (1H-tetrazol-5-yl)-4-biphenylylmethyl]-3H-imidazo[4,5-b]pyridine 9 is a potent angiotensin II receptor antagonist.
描述了所有可能的N-烷基化的2-正丁基-咪唑并[4,5]吡啶异构体的合成及其通过1 H NMR谱的结构分配。这些衍生物中的一种,即2-正丁基-3- [2'-(1H-四唑-5-基)-4-联苯基甲基] -3H-咪唑并[4,5-b]吡啶9是有效的血管紧张素II受体拮抗剂。
