3-Bromo-2-butoxy-5-methyl-pyridine (0.96 g, 3.9 mmol) was dissolved in toluene (6 mL). To this solution was added [2-fluoro-5-(trifluoromethyl)phenyl]-boronic acid (1.2 g, 5.9 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloro-methane complex (161 mg), and 2 N sodium carbonate solution (5.9 mL). The whole mixture was heated with stirring at 90° C. for 18 h, cooled to room temperature and eluted with ethyl acetate over 10 g ChemElut (Varian). The solvent was evaporated and the residue was purified by column chromatography on silica (n-heptane/ethyl acetate gradient) to yield 0.99 g of the title compound as a yellow oil, MS (ISP) 328.3 (M+H)+.
