Conditions

Temperature
160 °C

Procedure

1.5 g of 2-(4-diphenylaminophenyl)nitrobenzene and 20 ml of triethyl phosphate were heated and stirred at 160° C. for 8 hours. After triethyl phosphate was distilled off under reduced pressure, 10 ml of methanol was added, followed by filtration. The resulting solid was vacuum-dried to obtain 1.2 g of 2-diphenylaminocarbazole.
