Reaction Steps
4-Nitrobenzyl 7-[2-(2-formamidothiazol-4-yl)-2-pentyloxyiminoacetamido]-3-cephem-4-carboxylate (syn isomer, 8 g.), 10% palladium carbon (3.6 g.), methanol (36 ml.), tetrahydrofuran (90 ml.), acetic acid (0.63 g.) and water (6.3 ml.) were treated in a similar manner to that of Example 15 -(2) to give 7-[2-(2-formamidothiazol-4-yl)-2-pentyloxyiminoacetamido]-3-cephem-4-carboxylic acid (syn isomer, 3.4 g.).
