LiBH4 (1.94 mL, 3.88 mmol, 2 M in THF) was added to a stirred solution of methyl(4-cyano-3-fluorophenyl)acetate (0.50 g, 2.59 mmol) in THF (25 ml) at 0° C. The resulting solution was stirred for 12 h. Water (10 ml) was added, and the resulting solution was extracted with dichloromethane (2×50 ml). The combined organic layers were dried over MgSO4, filtered, and evaporated under reduced pressure. The residue was purified by column chromatography eluting with EtOAc-Hexanes (7:3→1:1) to give the product as colorless oil. 1H NMR (500 MHz, CDCl3) δ 7.60 (dd, J=7.4, J=7.1 Hz, 1H), 7.30 (s, 1H), 7.18 (dd, J=7.3, J=9.1 Hz, 1H), 3.95 (t, J=6.2 Hz, 2H), 2.93 (t, J=6.3 Hz, 2H).
