tert-Butyl ({5-(2-cyanopyridin-3-yl)-1-[(6-methoxypyridin-3-yl)sulfonyl]-1H-pyrrol-3-yl}methyl)methylcarbamate (235 mg) was dissolved in ethyl acetate (2 mL) and ethanol (2 mL), and 4 mol/L hydrogen chloride-ethyl acetate solution (4 mL) was added. After stirring at room temperature for 2 hr, the reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from ethanol to give the title compound as colorless crystals (yield 161 mg, 79%).
