Procedure

To propane-1-sulfonic acid (4-fluoro-3-hydroxymethyl-phenyl)-amide (671, 0.483 g, 0.00195 mol) in tetrahydrofuran (10.0 mL), cooled with ice/water, was added Dess-Martin periodinane (1.00 g, 0.00236 mol). The reaction was stirred at room temperature for 10 minutes. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 30% ethyl acetate in hexane to give a white solid (672, 360 mg, 75%). MS (ESI) [M−H+]−=244.1.
