実験手順

1-(4-Trifluoromethylphenyl)-2(1H,3H)-imidazolone (1.15 g) was dissolved in 20 ml of acetic acid. 10% Palladium-carbon (0.3 g) was added thereto and the mixture was stirred under a hydrogen stream for six hours. The catalyst was filtered off, the solvent was distilled off and the residue was recrystallized from ethyl acetate-diisopropyl ether to give 0.95 g of 1-(4-trifluoromethylphenyl)-2-imidazolidinone as colorless prisms.
