2-Propyl-8-oxo-1-[(2′-(1H-tetrazole-5-yl) biphenyl-4-yl)methyl]-4, 5, 6, 7-tetrahydrocyclohept imidazole (KT3-671), which has been found to be a potent and selective angiotesin II receptor antagonist, was synthesized in 14C-labelled form by using potassium[14C]-cyanide. [14C](KT3-671) 9 with a specific activity of 1.74GBq/mmol was prepared in four steps in 29.8% overall radio-chemical yield from potassium[14C]-cyanide.
2-丙基-8-氧-1-[(2′-(1H-四氮唑-5-基)联苯-4-基)甲基]-4, 5, 6, 7-四氢环庚咪唑(KT3-671),已被发现是一种强效且选择性的血管紧张素II受体拮抗剂,通过使用氰化钾[14C]合成了14C标记形式。特异活度为1.74GBq/mmol的[14C](KT3-671)在四个步骤中制备而成,总放射化学收率为29.8%,来源于氰化钾[14C]。
