PROCEDURE

实验过程

To a solution of benzhydryl 7-[2-(2-formamidothiazol-4-yl)-2-methoxyiminoacetamido]-3-chloromethyl-3-cephem-4-carboxylate (syn isomer) (25.0 g) in ethyl acetate (300 ml) was added a solution of triphenylphosphine (21.0 g) in tetrahydrofuran (170 ml), and the mixture was heated under reflux for 10 hours. The precipitated substance was collected by filtration to give [7-{2-(2-formamidothiazol-4-yl)-2-methoxyiminoacetamido}-4-benzhydryloxycarbonyl-3-cephem-3-yl]methyl-triphenylphosphonium chloride (syn isomer) (17.7 g). The remained filtrate was heated under reflux for 10 hours. Similarly, the precipitated substance was collected by filtration to recover the same product (9.75 g). Further, this operation was repeated once to recover the same product (3.3 g). Total yield: 30.75 g.
