Abstract

PURPOSE: To obtain the titled compound having acid stability and antimicrobial activities safely and efficiently, by reacting a 7-aminocephalosporanic acid derivative or its salt with a 2-furanyl-2-methoxyimino-acetic acid derivative.
CONSTITUTION: A compound shown by the formula I (R1 is halogen, azide, acetoxy, or benzimidazolethio) or its salt [e.g., 7-amino-3-(benzimidazole-2-yl)thiomethyl-3-cephem-4-carboxylic acid, etc.] is reacted with a compound shown by the formula II in a solvent e.g., N,N-dimethylformamide, etc. at 10W100°C, to give a compound shown by the formula III. The compound shown by the formula II as a starting raw material is obtained by reacting 1-(2-carboxylethyl)tetrazole-50thiol or its derivative with 2-furanyl-2-methoxyimino-acetic acid or its derivative in a solvent at -50°CW100°C.
