4-(Methoxymethyl)benzonitrile (6.0 g, 40.82 mmol) was dissolved in THF/diethyl ether (1:1, 60 mL) and the resulting solution was cooled to −10° C. 3 M solution of methyl magnesium iodide (13.57 g, 81.63 mmol) was added and the resulting mixture was stirred at this temperature for 5 hours. After completion of the reaction (TLC; toluene/methanol, 97:3), the mixture was poured into acidified water (50 mL; pH 3-4) and extracted with ethyl acetate (3×50 mL). The separated organic layers were combined, dried over Na2SO4 and concentrated in vacuo. The crude compound was purified by gradient flash chromatography, eluting with 8% ethyl acetate in hexane to afford the target compound (3.7 g, 55%).
