Procedure

To a solution of 6-chloronicotinonitrile (1.39 g, 10 mmol) in 100 mL of THF was added (4-methoxyphenyl)magnesium bromide (15 mmol) dropwise at 0° C. The mixture was then stirred at 0° C. for 1 h. and then 50 mL sat. NH4Cl solution was added. The mixture was extracted with ethyl acetate and the organic layer was washed with brine, dried over Na2SO4, filtered, concentrated, and purified by flash chromatography to give the product (1.24 g, 50% yield).
