Reaction Steps
4-Nitrobenzyl 7-[2-(2-formamidothiazol-4-yl)-2-cyclohexyloxyiminoacetamido]-3-cephem-4-carboxylate (syn isomer, 2.0 g.), 10% palladium carbon (0.8 g.), methanol (8 ml.), tetrahydrofuran (20 ml.), acetic acid (0.14 ml.) and water (1.4 ml.) were treated in a similar manner to that of Example 15-(2) to give 7-[2-(2-formamidothiazol-4-yl)-2-cyclohexyloxyiminoacetamido]-3-cephem-4-carboxylic acid (syn isomer, 0.77 g.).
