Participants

Reaction Conditions

Reaction Steps

To a solution of dihydroimidazolone 1a (1.0 g, 11.9 mmol) in 24 mL 1M AlCl3 in nitrobenzene was added 2-nitrobenzoyl chloride (2.2 g, 11.9 mmol), and the reaction was heated in a 65° C. oil bath for 6 h. The reaction was poured over ice during which a solid formed. The reaction was filtered through a sintered glass funnel and the solid washed with water and diethyl ether and dried in vacuum dessicator to give 1.26 g (45% yield) of 4-nitrobenzoyl-1,3-dihydroimidazol-2-one 1b.
