Yield	Reaction Conditions	Operation in experiment
	aluminium trichloride; In nitrobenzene;	EXAMPLE 14 4-Benzoyl-1,3-dihydro-2H-imidazol-2-one To 51 ml of nitrobenzene is added 1.68 g of 1,3-dihydro-2H-imidazol-2-one, 5.3 g of aluminum chloride and 3.1 g of benzoyl chloride. The mixture is stirred for 3 hours at 60° C. and poured into ice water. The solids are filtered, washed with ether and recrystallized twice from methyl alcohol-water to afford the title compound.
