Reaction Steps

A slurry of sodium hydride (50% in oil, 960 mg) in 100 ml of dimethylformamide is treated with 3,6-dicyanocarbazole (4.34 g, see Example 1) and heated at 110° C for two hours. The reaction mixture is then treated dropwise with benzylbromide (3.42 g) and heated at 110° C for an additional 18 hours. The reaction mixture is poured into water and extracted several times with dichloromethane. The combined dichloromethane extracts are dried over sodium sulfate and filtered through 200 ml of silica gel to yield 4.9 g of the title compound, melting point 265°-267° C.
