tert-Butyl ((5-(2-fluorophenyl)-1-((3-((tetrahydro-2H-pyran-2-yl)oxy)phenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 1g (0.45 g, 0.83 mmol) was dissolved in 5 mL of methanol, followed by addition of p-toluenesulfonic acid (16 mg, 0.08 mmol), and then the reaction solution was stirred for 3 h. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography with elution system B to obtain the title product tert-butyl ((5-(2-fluorophenyl)-1-((3-hydroxyphenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 1h (0.35 g, a red oil) in 92% yield.
