Procedure
4-Nitrobenzyl 7-[2-(2-formamidothiazol-4-yl)-2-isobutoxyiminoacetamido]-3-cephem-4-carboxylate (syn isomer, 14.2 g.), 10% palladium carbon (5.7 g.), methanol (57 ml.), tetrahydrofuran (142 ml.), acetic acid (1 ml.) and water (10 ml.) were treated in a similar manner to that of Example 15-(2) to give 7-[2-(2-formamidothiazol-4-yl)-2-isobutoxyiminoacetamido]-3-cephem-4-carboxylic acid (syn isomer, 4.25 g.).
