Procedure

A solution of 7β-[2-(2-tritylaminothiazol-4-yl)-(Z)-2-isopropoxyiminoacetamido]-3-[(1-amino-1H-tetrazol-5-yl)thiomethyl]-3-cephem-4-carboxylic acid (2.90 g, 3.7 mmol) in 80% formic acid (12 ml) was treated in a manner similar to that described in Example 6, (d) to give pale brown powder of 7β-[2-(2-aminothiazol-4-yl)-(Z)-2-isopropoxyiminoacetamido]-3-[(1-amino-1H-tetrazol-5-yl)thiomethyl]-3-cephem-4-carboxylic acid (0.83 g, 41.5%).
