PROCEDURE

实验过程

A mixture of 7-[2-(2-propynyloxyimino)-2-{2-(2,2,2-trifluoroacetamido)thiazol-4-yl}acetamido]-3-[1-(2-carboxy-2-methoxyiminoethyl)-1H-tetrazol-5yl]thiomethyl-3-cephem-4-carboxylic acid (syn isomer: in the 7-position) (2.0 g) and sodium acetate.trihydrate (3.71 g) in water (15 ml) was stirred overnight at room temperature. The solution was adjusted to pH 2.5 with 10% hydrochloric acid under ice-cooling and the resultant precipitates were filtered and washed with water to give 7-[2-(2-propynyloxyimino)-2-(2-aminothiazol-4-yl)acetamido]-3-[1-(2-carboxy-2-methoxyiminoethyl)-1H-tetrazol-5-yl]thiomethyl-3-cephem-4-carboxylic acid (syn isomer: in the 7-position). (1.12 g).
