Procedure

Platinic oxide (0.4 g.) was added to a solution of benzyhydryl 7-[2-methoxyimino-2-(2-aminothiazol-4-yl)acetamido]-3-(4-nitrobenzoyloxymethyl)-3-cephem-4-carboxylate (syn isomer) (4.3 g.) in a mixture of ethanol (50 ml.) and tetrahydrofuran (50 ml.), and the suspension was subjected to catalytic reduction at ambient temperature under ordinary pressure for 3 hours. After removing the catalyst from the resultant mixture by filtration, the filtrate was evaporated under reduced pressure. The residue was dissolved in ethyl acetate and the solution was washed with a saturated aqueous solution of sodium chloride, dried over magnesium sulfate and evaporated in vacuo. The residue was pulverized with diethyl ether to give benzhydryl 7-[2-methoxyimino-2-(2-aminothiazol-4-yl)acetamido]-3-(4-aminobenzoyl-oxymethyl)-3-cephem-4-carboxylate (syn isomer) (3.0 g.).
