Reaction Steps

A mixture of 15.3 g (37 mmol) of 3,8-dibromo-11,12-dihydroindolo[2,3-a]carbazole, 18.3 g (92.4 mmol) of biphenyl-2-ylboronic acid, 0.86 g (0.8 mmol) of Pd(PPh3)4, 55 ml of 2M Na2CO3, 100 ml of EtOH and 200 ml toluene was degassed and placed under nitrogen, and then heated at 100° C. for 24 h. After finishing the reaction, the mixture was allowed to cool to room temperature. The organic layer was extracted with ethyl acetate and water, dried with anhydrous magnesium sulfate, the solvent was removed and the residue was purified by column chromatography on silica to give product (12.2 g, 21.8 mmol, 59%).
