Procedure

To a solution of methyl 5-{[4-{[(tert-butoxycarbonyl)(methyl)amino]methyl}-3-fluoro-2-(2-fluoropyridin-3-yl)-1H-pyrrol-1-yl]sulfonyl}-2-furoate (260 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 hr. The reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from a mixed solvent of ethyl acetate-ethanol to give the title compound as a white solid (yield 177 mg, 78%).
