Procedure

16.5 ml (0.3 mmol) of an aqueous solution of potassium carbonate having a concentration of 2M and 0.4 g (0.1 mmol) of 1,1′-bis(diphenylphosphino)ferrocene palladium(II) dihydrochloride are added under a stream of nitrogen to a solution containing 2.0 g (0.1 mmol) of 2-bromopyridine-4-methanol and 2.2 g (0.1 mmol) of 2-(trifluoromethyl)phenylboronic acid in 30 ml of toluene. The mixture is stirred at 80° C. for 5 hours then 20 ml of water are added. After extraction with ethyl acetate, the organic phase is dried over sodium sulphate, filtered and evaporated. The residue obtained is purified by chromatography over silica gel eluted with a 60/40 heptane/ethyl acetate mixture. 2.3 g (85%) of [2-(2-trifluoromethylphenyl)pyridin-4-yl]methanol are obtained in the form of a yellow oil.
