Procedure
To a solution of tert-butyl {[1-{[5-(difluoromethyl)-2-furyl]sulfonyl}-4-fluoro-5-(2-fluoropyridin-3-yl)-1H-pyrrol-3-yl]methyl}methylcarbamate (154 mg) in ethyl acetate (2 mL) and 2-propanol (1 mL) was added 4 mol/L hydrogen chloride-ethyl acetate solution (3 mL), and the mixture was stirred at room temperature for 1.5 hr. The reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from a mixed solution of ethyl acetate-ethanol to give the title compound as a white solid (yield 96.3 mg, 72%).
