Reaction Steps

30.2 g (34.0 mmol) of tert-butyl 7-{10-(4,6-diphenyl-1,3,5-triazin-2-yl)-12,12-dimethyl-10,12-dihydro-10-azaindeno[2,1-b]fluorenyl}-12,12-dimethyl-12H-10-azaindeno[2,1-b]fluorene-10-carboxylate are dissolved in 900 ml of toluene and 200 ml of anisole, and 50 ml of trifluoroacetic acid are subsequently added. The mixture is stirred at 40° C. for 3 h and, when the reaction is complete, neutralised by means of ice-water and 20% NaOH solution. The mixture is extracted with dichloromethane, dried and recrystallised from toluene. The yield is 23.6 g (30 mmol, 88%).
