1.0 g (2.63 mmol) of 9-iodo-10-phenylanthracene, 542 mg (2.70 mmol) of p-bromophenylboronic acid, 46 mg (0.03 mmol) of Pd(PPh3)4, 3 ml (6 mmol) of 2 mol/L potassium carbonate (K2CO3) solution, and 10 ml of toluene were stirred for 9 hours at 80° C. After the reaction, toluene was added, and the mixture was filtered through Florisil, Celite, and alumina. The filtrate was washed with water and a saturated saline solution, then dried with magnesium sulfate. After natural filtration, the filtrate was concentrated, and recrystallized with chloroform and hexane. The target substance of 9-(4-bromophenyl)-10-phenylanthracene was obtained as a light brown solid, weighing 562 mg in a yield of 45% (synthesis scheme (j-6)).
