To a solution of 3-(4-(4-fluorophenoxyl)phenyl)acrylonitrile (5 g, 20.90 mmol) in ethanol (80 mL) was added NaBH4 (5.44 g, 144 mmol). The mixture was heated at 70° C. overnight. After cooling to room temperature, the reaction mixture was quenched with water (50 mL), and ethanol was removed under reduced pressure. The residue was partitioned between EA (100 mL) and water (50 mL). The organic phase was washed with saturated NaHCO3 solution (80 mL), brine (50 mL), dried over sodium sulfate, concentrated, and purified via flash chromatography to afford the title compound (4.7 g, 16.48 mmol, 79% yield) as a white solid. LCMS: rt=1.55 min, [M+H+]=242
