Sodium Hydroxide → 3-(4-(3-(Trifluoromethyl)phenoxy)phenyl)acrylonitrile

To a solution of (cyanomethyl)triphenylphosphonium bromide (8.61 g, 22.54 mmol) and NaOH (1.127 g, 28.2 mmol) in water (24 mL) and DCM (12 mL) was added 4-(3-(trifluoromethyl)phenoxy)benzaldehyde (5 g, 18.78 mmol) at 0° C. The mixture was stirred at room temperature for 4 h. DCM (50 mL) and water (50 mL) was added to the mixture, the organic phase was washed with water (50 mL), brine (50 mL), dried over anhydrous sodium sulfate and concentrated. Purification via flash chromatography afforded the title compound (5.07 g, 17.26 mmol, 92% yield) as pale yellow oil (slowly solidify to white solid). LCMS: rt=1.67 min, [M+H+]=290
