Reaction Conditions

Reaction Steps

3.7 g (9.2 mmol) of 3-bromo-9-(4-biphenylyl)carbazole, 63 mg (0.3 mmol) of palladium acetate, 330 mg (0.6 mmol) of 1,1-bis(diphenylphosphino)ferrocene, and 1.5 g (15 mmol) of sodium-tert-butoxide were put in a three-neck flask and the atmosphere of the flask was substituted by nitrogen, and then, 20 mL of dehydrated xylene was added, and deaeration was performed. Then, 9.3 g (10 mmol) of aniline was added thereto. Under a nitrogen atmosphere, it was heated and stirred at 130° C. for 4 hours. After the termination of the reaction, about 300 mL of hot toluene was added to this suspension, and the mixture was filtered through florisil, alumina, and Celite®. The obtained filtrate was concentrated and hexane was added thereto. Then, it was precipitated by ultrasonic wave. This was filtered, and the residue was dried to obtain 3.5 g (yield: 93%) of N-[(4-biphenylyl)carbazol-3-yl]-N-phenylamine (BCA) which was cream-colored powder.
