Reaction Steps

To 50 ml of nitrobenzene is added 4.2 g of 1,3-dihydro-2H-imidazol-2-one, 13.3 g of aluminum chloride and 7.2 g of furanoyl chloride. The mixture is stirred at 60° C. for 3 hours and poured over ice water. The solids are filtered, washed with ether and recrystallized twice from ethanol-water to afford the title compounds. M.P. 318°-321° C.
