2.69 g (5.46 mmol) of 10-ethyl-10H-phenanthro[9,10-b]carbazol-3-yl trifluoromethanesulfonate synthesized in Synthetic Example 9, 2.63 g (8.18 mmol) of dibiphenyl-4-ylamine, 0.04 g (0.16 mmol) of Pd(OAc)2, 0.20 g (0.33 mmol) of Binap, and 1.51 g (10.91 mmol) of K2CO3 were put, suspended in 30 ml of toluene, and refluxed and agitated for 12 hours. After the reaction was finished, extraction was performed by dichloromethane, filtering was performed by silica gel, and the column was used at a ratio of hexane:MC=4:1 (v/v) to obtain 2.83 g of N,N-di(biphenyl-4-yl)-10-ethyl-10H-phenanthro[9,10-b]carbazol-3-amine that was the target compound (yield 78%).
