Procedure

To a solution of 7β-amino-3-(trityl-1,2,3-triazol-4-ylthiomethylthio)-3-cephem-4-carboxylic acid diphenylmethyl ester (800 mg: 1.06 mMol.) and (Z)-2-(2-t-butoxycarbonylaminothiazol-4-yl)-2-(1-t-butoxycarbonyl-1-methylethoxyimino)acetic acid (479 mg: 1.12 mMol.) in dichloromethane (8 ml) cooling at -30° C. are added N-methylmorpholine (0.27 ml) (2.46 mMol.) and phenyl dichlorophosphate (0.19 ml: 1.27 mMol.), and the mixture is stirred at -30° C. for 50 minutes. The reaction mixture is mixed with 10% hydrochloric acid (1 ml), diluted with water, and extracted with ethyl acetate. The extract is washed with brine, dried over sodium sulfate, and concentrated. The residue is purified by silica gel column chromatography (toluene: ethyl acetate=10:1 to 5:1) to give 7β-[(Z)-2-(2-t-butoxycarbonylaminothiazol-4-yl)-2-(1-t-butoxycarbonyl-1-methylethoxyimino)acetamido]-3-(trityl-1,2,3-triazol-4-ylthiomethylthio)-3-cephem-4-carboxylic acid diphenylmethyl ester (855 mg) as yellow foam. Yield: 69%.
