実験手順

A solution of 7-amino-3-[1-(2-hydroxyethyl)-1H-tetrazol-5-ylthiomethyl]-3-cephem-4-carboxylic acid (2.0 g) and trimethylsilylacetamide (5.9 g) in dry ethyl acetate (40.0 ml) and a solution of 2-(2-formamidothiazol-4-yl)-2-propargyloxyiminoacetic acid (syn isomer, 1.6 g), dry dimethylformamide (0.5 g) and phosphoryl chloride (1.0 g) in dry ethyl acetate (52.0 ml) were treated in a similar manner to that of Example 1-(1) to give 7-[2-(2-formamidothiazol-4-yl)-2-propargyloxyiminoacetamido]-3-[1-(2-hydroxyethyl)-1H-tetrazol-5-ylthiomethyl]-3-cephem-4-carboxylic acid (syn isomer, 2.00 g).
