Reaction Steps

In a stream of argon, 0.71 g (3.21 mmol) of 9-phenanthreneboronic acid, 1.50 g (3.21 mmol) of 2-(3,5-dibromophenyl)-4,6-diphenyl-1,3,5-triazine and 37.0 mg (0.0321 mmol) of tetrakis(triphenylphosphine)palladium were suspended in a mixed solvent composed of 120 mL of toluene and 15 mL of ethanol, and the resultant suspension was heated to 60° C. and maintained at that temperature for 12 hours while being stirred. The obtained 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 obtained crude product was purified by silica gel chromatography using a hexane/chloroform (2:1) mixed solvent as an eluent to give 0.54 g of the target 4,6-diphenyl-2-[5-(9-phenanthryl)-3-bromophenyl]-1,3,5-triazine as a white solid (yield: 30%).
