Reaction Steps
A mixture of 7-[2-[2-(2,2,2-trifluoroacetamido)-thiazol-4-yl]-2-(4-methylbenzyloxyimino)acetamido]-3-cephem-4-carboxylic acid (syn isomer, 4.5 g.), sodium acetate 3 hydrate (12.5 g.), water (250 ml.) and tetrahydrofuran (20 ml.) was treated in a similar manner to that of Example 16-(2) to give 7-[2-(2-aminothiazol-4-yl)-2-(4-methylbenzyloxyimino)acetamido]-3-cephem-4-carboxylic acid (syn isomer, 0.84 g.), m.p. 135°-155° C. (dec.).
