Hydrogen chloride-ethyl acetate → 1-[5-({3-fluoro-2-(2-fluoropyridin-3-yl)-4-[(methylamino)methyl]-1H-pyrrol-1-yl}sulfonyl)-2-furyl]ethanone hydrochloride

Participants

Reaction Steps

To a solution of tert-butyl {[1-[(5-acetyl-2-furyl)sulfonyl]-4-fluoro-5-(2-fluoropyridin-3-yl)-1H-pyrrol-3-yl]methyl}methylcarbamate (180 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 ethyl acetate-ethanol to give the title compound as a white solid (yield 82.8 mg, 53%).
