Reaction Steps

10.0 g (59.8 mmol) of carbazole, 17.0 g (78.0 mmol) of 4-iodotoluene, 11.0 g (79.6 mmol) of potassium carbonate and 760 mg (12.0 mmol) of copper powder were allowed to react in 200 ml of diisopropylbenzene at 210° C. for 30 hours. The mixture was cooled to 80°-90° C., and filtered on sellaite. The filtrate was concentrated, and the residue was recrystallized from isopropanol to obtain 11.8 g of 9-p-tolylcarbazole.
