実験手順
2-(2,3-Dihydro-1,4-dithiin-5-yl)-2-methoxyiminoacetic acid (syn isomer, 1.2 g.) was allowed to react with 7-amino-3-(1-methyl-1H-tetrazol-5-yl)thiomethyl-3-cephem-4-carboxylic acid (1.65 g.) in a similar manner to that of Example 1 to give the captioned compound (2.1 g.), pale yellowish white powder.
