An amount of 3.74 g (10 mmol) of 9,10-diphenylanthracene-2-boronic acid synthesized in the same manner as in Exemplary Synthesis 1, 9.44 g (40 mmol) of p-dibromobenzene, and 300 mg of tetrakis triphenylphosphine palladium as catalysis were dissolved in a mixed solvent of 60 ml of toluene and 15 ml of ethanol. Then, 30 ml of 2M sodium carbonate solution was added and allowed to react at 90° C. for 12 hours. After the reaction was completed, the organic layer was separated and purified by column chromatography to obtain 2.32 g (5.15 mmol) of 2-(4-bromophenyl)-9,10-diphenylanthracene. The yield was 51.5%.
