Abstract
NEW MATERIAL:7-Glutaramide-3-(benzimidazol-2-yl)thiomethyl-3-cephem-4-carboxylic acid of formula I and its salts.
USE: Synthetic intermediate of drugs: for example, a compound of formula II, which is known as a very strong antibacterial, is derived from the compound in high efficiency and safety.
PREPARATION: A compound of formula III reacts with another compound of formula IV to give the compound of formula I. The reaction is conducted in an aqueous medium or a mix medium containing water and an organic solvent at temperatures of 10W100, preferably 30W80°C. The pH during the reaction is preferably kept to 3W10, much preferably 6W9 and the reaction time is about 30minW10hr.
