Procedure

To a stirred solution of (E)-4-(3-(3,5-dichlorophenyl)-4,4,4-trifluorobut-1-enyl)-2-fluoro-N-(thietan-3-yl)benzamide (100 mg, 0.2159 mmol) in acetone/water (1:1, 5.0 mL) was added oxone (266 mg, 0.4319 mmol) and the resultant reaction mixture was stirred at ambient temperature for 4 h. The reaction mixture was diluted with water and extracted with EtOAc. The combined EtOAc layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure. Purification by flash column chromatography (SiO2, 100-200 mesh; eluting with 30% EtOAc/pet ether) afforded the title compound as an off white solid (70.0 mg, 66%): 1H NMR (400 MHz, CDCl3) δ 8.07 (t, J=8.4 Hz, 1H), 7.39 (t, J=1.6 Hz, 1H), 7.31 (d, J=1.2 Hz, 1H), 7.26 (m, 2H), 7.23 (m, 2H), 7.19 (d, J=1.6 Hz, 1H), 6.60 (d, J=16.8 Hz, 1H), 6.49 (dd, J=16.8, 7.6 Hz, 1H), 4.90 (m, 1H), 4.64 (m, 2H), 4.14 (m, 2H),; ESIMS m/z 493.83 ([M−H]−); IR (thin film) 1527, 1113, 801, 1167, 1321 cm−1.
