6.6 g (30.17 mmol) of 9, 7.28 g (30.17 mmol) of 1-bromo-4-hexylbenzene, 21.63 g (66.39 mmol) of caesium carbonate, 78 mg (0.3 mmol) of bis-(acetonitrile)palladium(II) chloride and 431 mg (0.9 mmol) of 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl are dissolved in 90 ml of dioxane under nitrogen and heated at 100° C. overnight. 100 ml of water are added to the cooled solution, and the mixture is extracted twice with methyl t-butyl ether (100 ml). The combined organic phases are washed with water, dried over sodium sulfate and evaporated in vacuo. The residue is purified by column chromatography.
