Reaction Steps

24.8 g of 4-bromo-N-(2,6-diisopropylphenyl)naphthalene-1,8-dicarboximide and 7.5 g of copper(I) cyanide in 150 ml of N-methylpyrrolidone were heated at 210° C. for 4 hours. After cooling, water was added to the reaction mixture, producing a precipitate. The precipitate was filtered off, washed and dried. Column chromatography of the precipitate on silica gel (eluent: dichloromethane) gave 15.6 g of 4-cyano-N-(2,6-diisopropylphenyl)naphthalene-1,8-dicarboximide having a melting point of 291° C.
