Participants

Reaction Steps

14.07 g (57.18 mmol) of 3-bromo-9H-carbazole 22, 25.37 g (62.90 mmol) of compound 13 and 6.75 g of sodium carbonate are suspended in 1800 ml of dioxane, 1800 ml of toluene and 750 ml of water. 3.38 g (2.93 mmol) of Pd(PPh3)4 are added to this suspension. The reaction mixture is heated under reflux for 5 h. After cooling, the precipitated solid is filtered off with suction, washed with water and ethanol and dried. The residue is extracted with hot toluene and recrystallised from toluene. The yield is 19.5 g (65%).
