Reaction Steps

To a solution of methyl (2-chloro-4-cyano-3-methoxyphenyl)acetate (700 mg, 2.92 mmol) in THF (30 mL) was added 2M lithium borohydride (1.46 mL, 2.92 mmol) and the reaction was stirred at RT for 16 hours. The reaction was diluted with ether and quenched into water containing 2N HCl. The mixture was extracted twice with ethyl acetate and the organic layers were washed with brine, dried over sodium sulfate and concentrated in vacuo. The product mixture was separated by flash chromatography (10-40% ethyl acetate/hexanes) to afford the title product. 1H-NMR (400 MHz, CDCl3) δ ppm 3.10 (t, J=6.4 Hz, 2H), 3.94 (t, J=6.4 Hz, 2H), 4.08 (s, 3H), 7.175 (d, J=7.8 Hz, 1H), 7.46 (d, J=7.8 Hz, 1H).
