Reaction Steps

2.0 g of 1-(3-benzyloxy-4-methoxybenzoyl)-2-pyrrolidinone are hydrogenated in 60 ml of absolute methanol with 0.5 g of 5% palladium/carbon under atmospheric pressure and at room temperature. The catalyst is filtered off and the filtrate is concentrated and stirred with diethyl ether. After filtration, there is obtained 1-(3-hydroxy-4-methoxybenzoyl)-2-pyrrolidinone of melting point 123°-125° C.
