Procedure
To a solution of benzhydryl 7-[2-methoxyimino-2-(2-formamidothiazol-4-yl)acetamido]-3-(1-imidazolyl)carbonyloxymethyl-3-cephem-4-carboxylate (syn isomer) (13.5 g) in tetrahydrofuran (200 ml) was added m-chloroperbenzoic acid (5.8 g) with stirring under ice-cooling, followed by stirring for an hour at 5° C. The reaction mixture was evaporated and the residue was pulverized in diethyl ether, collected by filtration, washed with ethyl acetate and diethyl ether and then dried to give benzhydryl 7-[2-methoxyimino-2-(2-formamidothiazol-4-yl)acetamido]-3-(1-imidazolyl)carbonyloxymethyl-3-cephem-4-carboxylate-1-oxide (syn isomer) (11.0 g).
