Reaction Steps

2-Chloro-5-[hydroxy-(4-trifluoromethoxy-phenyl)-methyl]-benzenesulfonamide is dissolved in acetone (10 mL), and treated with a solution of Jones reagent (3 M in water, 0.91 mmol). The reaction is allowed to stir for 30 minutes. The reaction is diluted with water and extracted with dichloromethane. The organic phase is separated and concentrated in vacuo. The residue is purified by silica gel chromatography (gradient of ethyl acetate in hexanes 10-50%) affording 92 mg of the title compound. 1H NMR (CDCl3) 5.20 (s, 2H), 7.35 (d, 2H, J=8.3 Hz), 7.70 (d, 1H, J=8.3), 7.84 (d, 2H, J=8.7 Hz), 7.95 (dd, 1 h, J=1.9, 8.3), 8.48 (d, 1H, J=1.9). MS (m/z): 378 (M−1). CHN Calc C, 44.28; H, 2.39; N, 3.69. Found C, 43.97; H, 2.22; N, 3.60.
