実験手順

A mixture of 7-[2-(2-aminothiazol-4-yl)-2-methoxycarbonylmethoxyiminoacetamido]-3-vinyl-3-cephem-4-carboxylic acid (syn isomer) (2.0 g) and sodium bicarbonate (1.8 g) in water (40 ml) was stirred at 40° to 45° C. for 7 hours. The reaction mixture was adjusted to pH 5.0 with acetic acid. This solution was subjected to column chromatography on macroporous nonionic adsorption resin "Diaion HP-20" (20 ml) and eluted with water. The eluate was acidified to pH 2.2 with 10% hydrochloric acid under ice-cooling, The precipitates were collected by filtration and dried to give 7-[2-(2-aminothiazol-4-yl)-2-carboxymethoxyiminoacetamido]-3-vinyl-3-cephem-4-carboxylic acid (syn isomer) (0.9 g), which was identified by comparing the physico-chemical data with those of the object compound in Example 90.
