Reaction Steps

To a solution of 3-(3-formyl-pyridin-4-yl)-benzonitrile (30 mg, 0.15 mmol) in THF (1.5 mL) at −78° C. was added 0.5 M 3,4-dichlorophenylmagnesium bromide in THF (0.6 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 dichlordmethane to yield 3-{3-[(3,4-dichloro-phenyl)-hydroxy-methyl]-pyridin-4-yl}-benzonitrile as white crystals.
