Procedure

To a solution of tert-butyl {[4-fluoro-5-(2-fluoropyridin-3-yl)-1H-pyrrol-3-yl]methyl}methylcarbamate (324 mg) in tetrahydrofuran (20 mL) was added sodium hydride (60% in oil, 121 mg) at room temperature, and the mixture was stirred for 10 min. 15-Crown-5 (664 mg) was added, morpholine-4-sulfonyl chloride (250 mg) was added and the mixture was further stirred for 2 hr. 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=4:1→3:2) to give the title compound as a colorless oil (yield 370 mg, 78%).
