Eight-tenths mole (157.6 g.) of 1,8-naphthalimide, 260 g. (1.15 m.) of 4-chloro-3-nitrobenzotrifluoride, 64 g. (0.46 m.) of anhydrous potassium carbonate, about 4 g. (0.024 m.) of potassium iodide, and 2400 ml. of dry N,N-dimethylformamide were allowed to reflux under a nitrogen atmosphere for about 8 hours. The reaction mixture was allowed to cool to room temperature and the reaction vessel was then chilled in an ice-bath. The resulting precipitate was filtered, washed with water, and dried in vacuo to yield crude 2-[2-nitro-4-(trifluoromethyl)phenyl]-1H-benz[de]isoquinoline-1,3-(2H)-dione.
