To a mixture 1-bromo-2-fluoro-3-nitrobenzene (800 mg, 3.6 mmol), potassium benzyltrifluoroborate (2.2 g, 10.9 mmol) and Cs2CO3 (3.6 g, 10.9 mmol) in dioxane/H2O (10:1, 18 mL) was added [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride (60 mg, 2 mol %) and the mixture was heated to 100° C. for 8 h. The mixture was cooled to RT, diluted with H2O and extracted with EtOAc. The combined extracts were washed with H2O, brine, dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel chromatography to give the title compound (520 mg, 62%).
