Step3. 1,3-Dibromobenzene (16 g, 64.9 mmol), 9-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-9H-carbazole b(6.0 g, 11.6 mmol), potassium acetate (saturated solution of 6.6 g in water) and tetrakis(triphenylphosphine)palladium (0) (380 mg) are heated to reflux in 150 mL of toluene overnight under nitrogen atmosphere. After cooling down, evaporation and column chromatography 9-(3′-bromo-[1,1′-biphenyl]-3-yl)-9H-carbazole (5.8 g) is obtained.
