Procedure

(a') To a suspension of 784 mg (3.294 mM) of (Z)-2-(N-ethylcarbamoyl)vinylmercaptan silver salt in 30 ml of acetonitrile was added 2.965 g (19.77 mM) of sodium iodide, and the mixture was stirred at room temperature for 5 minutes. To the mixture was added at 0° C. a solution of 2 g (2.53 mM) of benzhydryl 7β-2,2,2-trichloroethoxycarbonylamino-3-diphenylphosphoryloxy-3-cephem-4-carboxylate in 20 ml of acetonitrile, and the mixture was stirred at the same temperature for 30 minutes, and then some insoluble material was filtered. To the filtrate was added 100 ml of ethyl acetate, and the mixture was washed with a saturated aqueous sodium chloride solution (50 ml×3) and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was chromatographed over silica gel column (eluent; chloroform) to give 1.65 g of benzhydryl 7β-2,2,2-trichloroethyoxycarbonylamino-3-[(Z)-2-(N-ethylcarbamoyl)vinylthio]-3-cephem-4-carboxylate.
