Procedure

Under the nitrogen atmosphere, 2-(anthracen-9-yl)triphenylene (3.3 g) as the eleventh intermediate compound, N-bromosuccinimide (NBS) (1.7 g), iodine (0.1 g) and THF (25 ml) were added to a flask, and stirred at room temperature for 5 hours. An aqueous solution of sodium thiosulfate was added and the reaction was terminated. The precipitates were collected by suction filtration. The obtained solid was washed with methanol and subsequently with heptane and purified by silica gel column chromatography (solvent: toluene) to give 2-(10-bromoanthracen-9-yl)triphenylene (3.5 g) as a twelfth intermediate compound. The scheme is shown in the following “Reaction 22”.
