Procedure

A solution of (E)-5-(3-(3,5-dichlorophenyl)-4,4,4-trifluorobut-1-en-1-yl)-2-(1H-1,2,4-triazol-1-yl)benzonitrile (0.3 g, 0.71 mmol), sodium acetate (0.087 g, 1.065 mmol) and hydroxylammonium chloride (0.072 g, 1.065 mmol) in 9:1 ethanol/water mixture (10 mL) was stirred at 70° C. for 8 h. The reaction was cooled to ambient temperature, and the ethanol was evaporated. The residue was dissolved in water and extracted with EtOAc (2×). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated under reduced pressure to afford the title compound as an off white solid.
