In a stream of argon, 168 mg of 2-[3,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-4,6-bis(4-tert-butylphenyl)-1,3,5-triazine, 155 mg of 4-bromo-1,10-phenanthroline, 32 mg of lithium chloride and 23 mg of tetrakis(triphenylphosphine)palladium were suspended in a toluene (6.0 mL)/ethanol (1.5 mL) mixed solvent. 1.0 mL of a 2.0M aqueous sodium carbonate solution was added in the obtained suspension, and the mixture was stirred at 100° C. for 88 hours. Then the reaction mixture was left to be cooled to room temperature, and distilled under a reduced pressure to remove low-boiling point ingredients. Water was added to the residue to give a crude product. The crude product was collected by filtration, and evaporated to dryness under a reduced pressure. The dried crude product was recrystallized from a dichloromethane/hexane mixed solvent to give 169 mg of target 2-[3,5-bis(1,10-phenanthrolin-4-yl)phenyl]-4,6-bis(4-tert-butylphenyl)-1,3,5-triazine as a white solid (yield, 87%).
