Procedure

In the atmosphere of argon, 9.1 g of fluoranthene-3-boronic acid, 10.5 g of 4-bromoiodobenzene, 2.1 g of tetrakis(triphenylphosphine)palladium(0), 186 mL of toluene and 74 mL of an aqueous 2M solution of sodium carbonate were placed in a flask, and stirred at 100° C. for 8 hours. After cooling to room temperature, the reaction solution was extracted with toluene. After removing an aqueous phase, an organic phase was washed with saturated saline, and dried with anhydrous sodium sulfate. After filtration, the solvent was distilled off under reduced pressure, and residues were purified by silica gel column chromatography, whereby 9.2 g (yield 70%) of 3-(4-bromophenyl)fluoranthene as an intended product was obtained.
