氯甲酸苯酯
phenyl carbonochloridate
化合物简介
Phenyl chloroformate is a corrosive liquid that is used to synthesize Urazole, a five membered heterocyclic compound that reacts with aldoses to form α and β pyranosides and furanosides. Phenyl chloroformate is also used as a reagent to prepare Sorafenib, a multikinase inhibitor that targets the tumour and tumour vasculature in patients with melanoma.

生产方法及用途
生产方法
由苯酚与光气反应而得。将苯酚溶于氯仿,在冷却下通入光气,使吸收的光气量与苯酚等摩尔比,于5-10℃搅拌下滴加等摩尔的N,N-二甲基苯胺。然后加冷水稀释,分取油层,依次用稀盐酸和水洗涤。经无水氯化钙干燥后,蒸除氯仿,再减压蒸馏,收集74-75℃(1.73kPa)馏分,即氯甲酸苯酯。收率90%左右。
用途
农药、医药中间体,如富马酸扎莫特罗、利美尼啶、卡马西泮、对苯二甲醇、亮丙瑞林。
