Reaction Steps

2-Bromo-10-(biphenyl-4-yl)-9,9-dimethyl-7-phenylacridan (2.5 g), bis(biphenyl-4-yl)-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaboran-2-yl)phenyl]amine (3.0 g), toluene (37 ml), ethanol (9.3 ml), and a 2M potassium carbonate aqueous solution (7.2 ml) were added to a nitrogen-substituted reaction vessel and aerated with nitrogen gas for 30 min under ultrasonic irradiation. The mixture was heated after adding tetrakis(triphenylphosphine)palladium (0.11 g) and stirred at 72° C. for 8.5 hours. The mixture was allowed to cool to a room temperature, and methanol (40 ml) was added. A precipitated solid was collected by filtration and washed with water to obtain an orange crude product. The crude product was dissolved by adding toluene (360 ml), purified by adsorption using silica gel (3.6 g), and crystallized with toluene/methanol three times. Further, methanol (60 ml) was added to the product, and the product was washed and purified by heating under reflux to obtain a white powder of bis(biphenyl-4-yl)-[4-{10-(biphenyl-4-yl)-9,9-dimethyl-7-phenylacridan-2-yl}phenyl]amine (3.04 g; yield 75%).
