Procedure

A solution of 7-[2-methoxyimino-2-(5-amino-1,2,4-thiadiazol-3-yl)acetamido]-3-[1-{3-(N-t-butoxycarbonylamino)propyl}-1H-tetrazol-5-yl]thiomethyl-3-cephem-4-carboxylic acid (syn isomer) (2.22 g) in formic acid (22 ml) was stirred for 2.5 hours at ambient temperature. The reaction mixture was post-treated in a conventional manner to give 7-[2-methoxyimino-2-(5-amino-1,2,4-thiadiazol-3-yl)acetamido]-3-[1-(3-aminopropyl)-1H-tetrazol-5-yl]thiomethyl-3-cephem-4-carboxylic acid (syn isomer) (0.875 g), mp. 185° to 190° C. (dec.).
