Procedure

To a solution of tert-butyl [1-(5-phenyl-1-{[3-(1-methyl-1-hydroxyethyl)phenyl]sulfonyl}-1H-pyrrol-3-yl)methyl]carbamate (334 mg) in ethanol (4 mL) was added 4 mol/L hydrogen chloride-ethyl acetate solution (4.0 mL) and the mixture was stirred at room temperature for 3 hr. After the reaction mixture was concentrated under reduced pressure, saturated aqueous sodium hydrogencarbonate solution was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogencarbonate solution, water and saturated brine, dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by basic silica gel column chromatography (eluent: ethyl acetate) to give the title compound as a white solid (yield 203 mg, 76%).
