PROCEDURE

实验过程

2-(2-Formamidothiazol-4-yl)-2-ethoxycarbonylmethoxyiminoacetic acid (syn isomer, 1.35 g.), 4-nitrobenzyl 7-amino-3-cephem-4-carboxylate (1.54 g.), N,N-dimethylformamide (393 mg.), phosphoryl chloride (825 mg.), tetrahydrofuran (21.2 ml.), acetone (3.9 ml.) and water (3.9 ml.) were treated in a similar manner to that of Example 15-(1) to give 4-nitrobenzyl 7-[2-(2-formamidothiazol-4-yl)-2-ethoxycarbonylmethoxyiminoacetamido]-3-cephem-4-carboxylate (syn isomer 2.52 g.).
