9-Phenyl-9H,9′H-[3,3′]bicarbazolyl (12.9 g), 4-bromo-iodobenzene (13.4 g), a copper powder (0.64 g), potassium carbonate (8.34 g), sodium bisulfite (0.49 g), and orthodichlorobenzene (50 ml) were added to a nitrogen-substituted reaction vessel, heated, and stirred at 170° C. for 19.5 hours. The mixture was cooled to 90° C., and dissolved after adding toluene (200 ml). After removing the insolubles by filtration, the filtrate was concentrated under reduced pressure, and crystallized from methanol (50 ml) to obtain a white powder of 9-(4-bromophenyl)-9′-phenyl-9H,9′H-[3,3′]bicarbazolyl (17.30 g; yield 97%).
