As depicted in Reaction 5, 15 g (46 mmol) of 3,6-dibromocarbazole, 14 g (92 mmol) of phenylboronic acid, K2CO3 (2 mol), Pd(PPh3)4 and toluene were refluxed for 10 hours. The reaction mixture was extracted with methylene chloride. The solvent was removed, and then the residue was purified by column chromatography (eluent:hexane) to give the title compound. Yield: 73%. MS (EI) (Calcd. for C24H17N, 319.14. Found: 319).
