Participants

Reaction Steps

150 mg of 1-(3-benzoyloxy-4-methoxybenzoyl)pyrrolin-2-one are dissolved in 100 ml of ethyl acetate and hydrogenated with hydrogen over 150 mg of 5% palladium/carbon at atmospheric pressure. The catalyst is filtered off and the filtrate is concentrated. The residue is stirred at room temperature in diethyl ether. After filtration, there is obtained 1-(3-hydroxy-4-methoxybenzoyl)-2-pyrrolidinone of melting point 122°-124° C.
