Abstract

PURPOSE: The reaction between 6-aroylaminopenicillanic acid 1-oxide and an alcohol is conducted in the presence of phosphonitrile chloride to produce the titled compound used as a synthetic intermediate of various kinds of penicillines or cephalosporins.
CONSTITUTION: The reaction of 6-aroylaminopenicillanic acid 1-oxide with an alcohol such as benzyhydrol is carried out in a solvent such as acetonitrile or dichloromethane in the presence of phosphonitrile chloride, (Cl2NP)n where n is integer, e.g., polymer of phosphonitrile dichloride, at room temperature, under cooling or heating for 1W5hr to give the objective compound in high yield.
