Reaction Steps
A mixture of 4-nitrobenzyl 7-[2-[2-(2,2,2-trifluoroacetamido)thiazol-4-yl]-2-(4-fluorobenzyloxyimino)acetamido]-3-cephem-4-carboxylate (syn isomer, 4.65 g.), 10% palladium carbon (2.3 g) in water (9.3 ml.), acetic acid (0.93 ml.), tetrahydrofuran (93 ml.) and methanol (93 ml.) were treated in a similar manner to that of Example 7-(2) to give 7-[2-[2-(2,2,2-trifluoroacetamido)thiazol-4-yl]-2-(4-fluorobenzyloxyimino)-acetamido]-3-cephem-4-carboxylic acid (syn isomer, 3.15 g.).
