実験手順

To a stirred mixture of 5.0 g of 8-(3-(trifluoromethyl)phenyl)-3H,6H-1,4,5a,8a-tetraazaacenaphthylene-3,5(4H)-dione (prepared as described in Example 14) in 50 ml of dry N,N-dimethylformamide, under nitrogen, is added 800 mg of 60 percent sodium hydride (dispersion in mineral oil). The mixture is stirred at room temperature for 2 hours, then 10 ml of iodoethane is added and stirring is continued for 48 hours. The reaction mixture is evaporated to dryness, then treated with water, and the gummy solid which is isolated is dissolved in chloroform and the extract dried over anhydrous sodium sulfate. Evaporation gives an oil which is triturated with diethyl ether-hexane to provide a yellow solid which is collected by filtration to give 2.0 g of the desired product as a white solid. The product is recrystallized from isopropyl alcohol, mp 161-163° C.
