Reaction Steps

71.5 grams of copper in powder form were added to 96.10 grams of 5,5-dimethyl-hydantoin and 170.86 grams of 2-nitro-5-chloro trifluoromethylbenzene. The mixture was heated to 200° C. for about 21 hours, the pressure being maintained at 450 millibars, then, was cooled to 20° C. and taken up in 480 ml of ethanol. The product was characterized and determined by thin layer chromatography of the ethanol solution.
