Procedure

1-[3,4-Bis(acetyloxy)benzoyl]-2-imidazolidinone (11 g, 0.035 mol) was suspended in a mixture of 50 ml of ethanol and 50 ml of water, 4.2 ml (0.07 mol) of aqueous ammonia solution was added with stirring. After 15 minutes, a clear solution was formed, which was evaporated to a small volume. 1-(3,4-Dihydroxybenzoyl)-2-imidazolidinone crystallized out yielding 6.1 g of the title compound, melting point 208°-210° C.
