[1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (1 : 1) (250mg) was added to a degassed mixture of 4,4,5,5-tetramethyl-2-(4-nitro-phenyl)-[1,3,2]dioxaborolane (1.67g, 6.70mmoles), 1-difluoromethoxy-4-iodo-benzene (2.17g, 8.04mmoles) and 2M aqueous cesium carbonate (10.05ml) in 1,4-dioxan (120ml). The mixture was placed under an argon atmosphere and was heated at 80C for 20 hours. After cooling, the mixture was concentrated and the residue was partitioned between dichloromethane (2 x 200ml) and water (100ml). The combined extracts were washed with brine (150ml) and dried (MgSO4). After evaporation of the solvent, the residue was purified by flash chromatography, using petrol (60-80)/diethyl ether 19 : 1v/v as eluent, to afford compound 168 (1.15g) as a beige coloured solid.
