Reaction Steps
A suspension of 10 g of 1-(3'-trifluoromethyl-4'-nitrophenyl)-4,4-dimethyl-5-imino-imidazoline-2-one, 35 ml of 22° Be aqueous hydrochloric acid and 35 ml of water was refluxed for an hour, cooled to 20° C and poured into water. The mixture was vacuum filtered and the recovered precipitate was washed and dried to obtain 9.5 g of 1-(3'-trifluoromethyl-4'-nitrophenyl)-4,4-dimethyl-imidazoline-2,5-dione melting at 149° C. A microanalytical sample after crystallization from ethanol melted at 149° C.
