Reaction Steps

30 g (57 mmol) (9,9-dimethyl-9H-fluoren-2-yl)-[4-(9-phenyl-9H-carbazol-3-yl)-phenyl]-amine and 20 g (57 mmol) 4-bromo-4′-iodo-biphenyl [105946-82-5] are dissolved in 200 ml toluene and treated with 100 ml of a 2 M solution of sodium carbonate. The reaction mixture is carefully degassed and 200 mg tetrakistriphenylphosphine palladiume are added and refluxed for 20 h. The reaction mixture is then cooled to room temperature and 250 ml water is added. The layers are separated. The water phase is then extracted three times with toluene. The organic layers are then washed twice with water, dried over magnesium sulphate, filtrated and the solvent is then removed under vacuum. The residue is recrystallized from butanole/toluene, to yield 29 g (38 mmol) (67%) of a white solid with a purity of 99.3%.
