PROCEDURE

实验过程

A mixture of benzhydryl 7-[2-(5-amino-1,2,4-thiadiazol-3-yl)-2-ethoxyiminoacetamido]-3-chloromethyl-3-cephem-4-carboxylate (syn isomer) (36.7 g) in ethyl acetate (600 ml), triphenyl phosphine (18.8 g) and sodium iodide (1 g) were boiled under reflux for 100 minutes. The precipitates were collected by filtration and washed with ethyl acetate to give [4-benzhydryloxycarbonyl-7-[2-(5-amino-1,2,4-thiadiazol-3-yl)-2-ethoxyiminoacetamido]-3-cephem-3-ylmethyl]triphenylphosphonium chloride (syn iosmer) (31.1 g).
