Procedure

To a solution of tert-butyl ({4-fluoro-5-(2-fluoropyridin-3-yl)-1-[(5-fluoropyridin-3-yl)sulfonyl]-1H-pyrrol-3-yl}methyl)methylcarbamate (224 mg) in ethyl acetate (2 mL) and 2-propanol (1 mL) was added 4N hydrogen chloride-ethyl acetate solution (3 mL), and the mixture was stirred at room temperature for 3 hr. The reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from ethyl acetate-ethanol to give the title compound as a white solid (yield 127 mg, 65%).

Workup

  1. concentrationThe reaction mixture was concentrated under reduced pressure
