Reaction Steps
7-[2-(2-Formamidothiazol-4-yl)-2-(3-tert-butoxycarbonylaminopropoxyimino)acetamido]-3-[1-(2-tert-butoxycarbonylaminoethyl)-1H-tetrazol-5-yl)thiomethyl-3-cephem-4-carboxylic acid (syn isomer, 2.8 g.), conc. hydrochloric acid (1.6 ml.) and methanol (60 ml.) were treated in a similar manner to that of Example 6-(2) to give 7-[2-(2-aminothiazol-4-yl)-2-(3-aminopropoxyimino)acetamido]-3-[1-(2-aminoethyl)-1H-tetrazol-5-yl]thiomethyl-3-cephem-4-carboxylic acid (syn isomer, 1.1 g.).
