A synthetic route for the preparation of 2-(benzylthio)-5-[1-(4-fluorobenzyl)-3-phenyl-1H-pyrazol-5-yl]-1,3,4-oxadiazoles derivatives from ethyl 3-phenyl-1H-pyrazole-5-carboxylate has been developed. The configurations of the intermediate 1,3,4-oxadiazole-2-thione and 3-bromobenzylthio substituted 1,3,4-oxadiazole were determined by single crystal X-ray diffraction analysis. The in vitro xanthine oxidase
3-苯基乙基制备2-(苄硫基)-5-[1-(4-氟苄基)-3-苯基-1H-吡唑-5-基]-1,3,4-恶二唑衍生物的合成路线-1H-pyrazole-5-carboxylate 已被开发出来。通过单晶 X 射线衍射分析确定中间体 1,3,4-恶二唑-2-硫酮和 3-溴苄硫基取代的 1,3,4-恶二唑的构型。评价了这些化合物的体外黄嘌呤氧化酶抑制活性。
