Procedure

In a stream of argon, 0.52 g (2.36 mmol) of 9-phenanthreneboronic acid, 0.91 g (2.15 mmol) of 2-(3-bromo-5-chlorophenyl)-4,6-diphenyl-1,3,5-triazine and 24.8 mg (0.022 mmol) of tetrakis(triphenylphosphine)palladium were suspended in a mixed solvent comprised of 80 mL of toluene and 10 mL of ethanol, and the temperature of the obtained suspension was elevated to 60° C. 6.45 mL (6.45 mmol) of an aqueous 1M K2CO3 solution was gradually added dropwise to the suspension, and the obtained mixture was distilled under reflux for 18 hours. The resultant reaction mixture was cooled to room temperature, and then distilled under a reduced pressure to remove all volatile materials. Methanol was added to the concentrate, and the thus-deposited solid was collected by filtration. The thus-obtained crude product was dissolved in chloroform and the obtained solution was filtered by celite. The filtrate was distilled to remove all volatile materials to give 1.02 g of an intermediate 2-[3-chloro-5-(9-phenanthryl)phenyl]-4,6-diphenyl-1,3,5-triazine as grayish white solid (yield: 91%).
