Procedure

To a solution of tert-butyl {[4-fluoro-5-(2-fluoropyridin-3-yl)-1H-pyrrol-3-yl]methyl}methylcarbamate (200 mg) in tetrahydrofuran (10 mL) was added sodium hydride (60% in oil, 50 mg), and the mixture was stirred at room temperature for 10 min. 4-(Benzyloxy)benzenesulfonyl chloride (210 mg) was added and the mixture was further stirred for 30 min. The reaction mixture was diluted with water, and extracted with ethyl acetate. The extract 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=7:3→1:1) to give the title compound as a colorless oil (yield 360 mg, quantitative).
