Procedure
To a solution of 3-(3-formyl-pyridin-4-yl)-benzonitrile (15 mg, 0.075 mmol) in THF (1 mL) at −78° C. was added 0.5 M 4-methylphenylmagnesium bromide in THF (0.3 mL). The reaction mixture was quenched with ammonium chloride and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, concentrated, and the residue purified-by flash chromatography eluted with 5% methanol in dichloromethane to yield 3-{3-[hydroxy-(2-methyl-phenyl)-methyl]-pyridin-4-yl}-benzonitrile as white crystals.
