| titleOfInvention | Novel preparative method of cephalosporanic acid derivative |
| abstract | PURPOSE: A 7-aminocephalosporanic acid derivative is made to react with a novel active ester to safely produce the titled derivative used as an antibiotic agent against grampositive and -negative bacteria in high yield. n CONSTITUTION: The reaction between a 7-aminocephalosporanic acid derivative of formula I (R 1 is halogen, azide, benzimidazole) and 2-amino-1,3-thiazol-4-yl-acetic 1-dimethylaminoethyl-tetrazol-5-yl thiol ester is conducted, preferably at a molar ratio of 1:(1W2) in a solvent of DMF at 40W80°C to give the objective cephalosporanic acid derivative or its salt of formula III. The compound of formula II is novel and obtained, e.g., by reaction of 1-dimethylaminoethyl-tetrazole-5-thiol of formula IV with 2-amino-1,3-thiazol-4-ylacetic acid in a solvent at -50W+100°C. n COPYRIGHT: (C)1981,JPO&Japio |
