실험 절차

To a solution of tert-butyl [(4-fluoro-5-(2-fluoropyridin-3-yl)-1-{[5-(hydroxymethyl)-2-furyl]sulfonyl}-1H-pyrrol-3-yl)methyl]methylcarbamate (223 mg) in dichloromethane (5 mL) was added diethylaminosulfur trifluoride (78.7 mg) under ice-cooling, and the mixture was stirred at room temperature for 18 hr. Saturated aqueous sodium hydrogen carbonate solution was added and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=4:1→2:1) to give the title compound as a pale-yellow oil (yield 166 mg, 57%).
