A mixture of 1.0 g (2.63 mmol) of 9-iodo-10-phenylanthracene, 542 mg (2.70 mmol) of p-bromo phenylboronic acid, 46 mg (0.03 mmol) of tetrakis(triphenylphosphine)palladium(0) (abbreviation: Pd(PPh3)4), 3 mL (6 mmol) of potassium carbonate aqueous solution (2 mol/L), and 10 mL of toluene was stirred for nine hours at 80° C. After reaction, toluene was added and filtration was carried out using florisil, celite, and alumina. A filtrate was washed with water and saturated saline, and then dried with magnesium sulfate. After the mixture was subjected to natural filtration, the filtrate was concentrated, and when it was recrystallized with chloroform and hexane, 562 mg of 9-phenyl-10-(4-bromophenyl)anthracene that was a target substance is obtained as a light brown solid at a yield of 45% (Synthesis scheme (b-4)).
