1.0 g (2.63 mmol) of 9-iodo-10-phenylanthracene, 542 mg (2.70 mmol) of 4-(4-bromophenyl)phenylboronic acid, 46 mg (0.03 mmol) of tetrakis(triphenylphosphine)palladium, 3 mL (6 mmol) of potassium carbonate solution (2.0 mol/L), and 10 mL of toluene were stirred for 9 hours at 80° C. After reaction, toluene was added, and it was filtered through florisil®, celite, and alumina. The filtrate was washed with water and saturated saline, and then dried with magnesium sulfate. After natural filtering, the filtrate was concentrated, and when recrystallization was performed with a mixture of chloroform and hexane, 562 mg of 9-[4-(4-bromophenyl)phenyl]-10-phenylanthracene (PBA) that was a target substance and was a light brown solid was obtained in a yield of 45% (Synthesis Scheme (e-2)).
