Reaction Steps
The resulting 10-(biphenyl-4-yl)-12,12-dimethyl-10,12-dihydroindeno[2,1-b]carbazole (42.5 g) and DMF (2.5 L) were added to a reaction vessel, and the mixture was heated up to 70° C. and dissolved. After cooled to a room temperature, N-bromo-succinimide (17.4 g) was added, and the mixture was stirred for 7 hours. Water (2.5 L) was added, and filtration was performed to obtain a white powder of 10-(biphenyl-4-yl)-7-bromo-12,12-dimethyl-10,12-dihydroindeno[2,1-b]carbazole (34.9 g; yield 69.5%).
