Procedure

tert-Butyl ({4-fluoro-5-(2-fluoropyridin-3-yl)-1-[(2-methyl-3-furyl)sulfonyl]-1H-pyrrol-3-yl}methyl)methylcarbamate (187 mg) was dissolved in ethyl acetate (1 mL) and ethanol (1 mL), and 4 mol/L hydrogen chloride-ethyl acetate solution (2 mL) was added. The mixture was stirred at room temperature for 2 hr, and the reaction mixture was concentrated under reduced pressure. The residue was recrystallized from a mixed solvent of ethyl acetate-ethanol=3:1 to give the title compound as colorless crystals (yield 125 mg, 78%).
