실험 절차

To a suspension of sodium hydride (60% in oil, 34 mg) in tetrahydrofuran (4 mL) were added dropwise 15-crown-5 (0.17 mL), a solution of tert-butyl {[4-fluoro-5-(2-fluoropyridin-3-yl)-1H-pyrrol-3-yl]methyl}methylcarbamate (210 mg) in tetrahydrofuran (1 mL) and 2-methylfuran-3-sulfonyl chloride (176 mg) under ice-cooling, and the mixture was stirred for 0.5 hr. The reaction mixture was diluted with water, and extracted with ethyl acetate. The separated aqueous layer was extracted again with ethyl acetate. The combined 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=9:1→2:3) and basic silica gel column chromatography (eluent: hexane-ethyl acetate=17:3→1:1) to give the title compound as a pale-yellow oil (yield 187 mg, 61%).
