PROCEDURE

实验过程

7-[2-(2-Formamidothiazol-4-yl)-2-(2-chloroethoxyimino)acetamido]-3-cephem-4-carboxylic acid (syn isomer, 1.8 g.), conc. hydrochloric acid (1.6 g.), methanol (27 ml.) and tetrahydrofuran (40 ml.) were treated in a similar manner to that of Example 15-(3) to give 7-[2-(2-aminothiazol-4-yl)-2-(2-chloroethoxyimino)-acetamido]-3-cephem-4-carboxylic acid (syn isomer, 1.4 g.).
