To a solution of tert-butyl {[1-[(2-chlorophenyl)sulfonyl]-5-(2-cyanopyridin-3-yl)-1H-pyrrol-3-yl]methyl}methylcarbamate (211 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 2 hr. The reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from a mixed solvent of ethanol-water to give the title compound as a white solid (yield 144 mg, 78%).
