Procedure
2-n-Propoxyimino-2-(2-formamido-1,3-thiazol-4-yl)acetic acid (syn isomer) (1.73 g.) and 7-amino-3-(1-carboxymethyl-1H-tetrazol-5-yl)thiomethyl-3-cephem-4-carboxylic acid (2.0 g.) were reacted according to similar manners to those of Examples 1(b), 2(b), 3(b) and 6(b) to give white powder of 7-[2-n-propoxyimino-2-(2-formamido-1,3-thiazol-4-yl)acetamido]-3-(1-carboxymethyl-1H-tetrazol-5-yl)thiomethyl-3-cephem-4-carboxylic acid (syn isomer) (2.32 g.).
