Reaction Conditions

Reaction Steps

3,6-Diphenylcarbazole (2.80 g, 8.77 mmol), 1-bromo-3-iodobenzene (22.18 g, 87.7 mmol), copper powder (0.279 g) and potassium carbonate (4.85 g) were mixed together, and the mixture was heated in a nitrogen atmosphere at 190° C. for 9 hours. The resultant mixture was cooled to room temperature and diluted with methylene chloride, followed by washing with water and drying, to thereby obtain a pale brown liquid. Next, the obtained liquid is purified through silica gel column chromatography using a solvent mixture of methylene chloride/hexane (2/3 by volume), to thereby obtain 3.59 g of 9-(3-bromophenyl)-3,6-diphenylcarbazole.
