PROCEDURE

实验过程

7-[2-(2-Formamidothiazol-4-yl)-2-(2-chloroethoxyimino)acetamido]-3-(1,3,4-thiadiazol-2-yl)thiomethyl-3-cephem-4-carboxylic acid (syn isomer, 2.0 g.) was treated with conc. hydrochloric acid (0.7 g.) in a similar manner to that of Example 24-(2) to give 7-[2-(2-aminothiazol-4-yl)-2-(2-chloroethoxyimino)acetamido]-3-(1,3,4-thiadiazol-2-yl)thiomethyl-3-cephem-4-carboxylic acid (syn isomer, 1.53 g.).
