The resulting 12,12-dimethyl-10-(9,9-dimethyl-9H-fluorene-2-yl)-10,12-dihydroindeno[2,1-b]carbazole (7.0 g) and DMF (140 ml) were added to a reaction vessel. The mixture was heated up to 100° C., dissolved, and cooled. N-bromo-succinimide (2.6 g) was added under ice-cooled conditions, and the mixture was stirred for 1 hour at a room temperature. Water (500 ml) was added, and the mixture was subjected to filtration to obtain a pale red powder of 7-bromo-12,12-dimethyl-10-(9,9-dimethyl-9H-fluorene-2-yl)-10,12-dihydroindeno[2,1-b]carbazole (5.7 g; yield 70.3%).
