PROCEDURE

实验过程

7-[2-Methoxyimino-2-(3-hydroxyphenyl)acetamido]-3-carbamoyloxymethyl-3-cephem-4-carboxylic acid (syn isomer) (1.98 g.) was suspended in water (15 ml.) and dissolved by adding sodium bicarbonate (0.35 g.) with stirring at ambient temperature. The solution was lyophilized and dried to give sodium 7-[2-methoxyimino-2-(3-hydroxyphenyl)acetamido]-3-carbamoyloxymethyl-3-cephem-4-carboxylate (syn isomer) (1.9 g.).
