Procedure

To a solution of 4-bromo-pyridine-3-carbaldehyde (400 mg, 2.15 mmol) in THF (10 mL) at −78° C. was added dropwise 3.0 M phenylmagnesium bromide solution in THF (1.08 mL). After 15 min, the reaction was quenched with saturated ammonium chloride solution and extracted with ethyl acetate, then purification by flash chromatography eluted with 50% ethyl acetate in hexane to yield (4-bromo-pyridin-3-yl)-phenyl-methanol as slight yellow crystals.
