実験手順

To propane-1-sulfonic acid (2-fluoro-3-hydroxymethyl-phenyl)-amide (66, 0.20 g, 0.81 mmol) in tetrahydrofuran (5.0 mL) was added Dess-Martin periodinane (0.377 g, 0.89 mmol). The reaction was stirred at room temperature for 10 minutes, then 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 20% ethyl acetate in hexane to give a white solid (67, 100 mg, 50.0%). MS (ESI) [M−H+]+=244.1.
