Procedure

tert-Butyl ((5-(2-fluorophenyl)-1-((3-((1-(methylcarbamoyl)cyclopropyl)methoxy)phenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 5d (100 mg, 0.18 mmol) was dissolved in 3 mL of dichloromethane, followed by addition of 1 mL of trifluoracetic acid, and then the reaction solution was stirred for 1 h. 10 mL of saturated sodium bicarbonate solution were added, and the reaction solution was extracted with dichloromethane (20 mL×2). The organic phases were combined, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by thin layer chromatography with elution system A to obtain the title product 1-((3-((2-(2-fluorophenyl)-4-((methylamino)methyl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)methyl)-N-methylcyclopropylcarboxamide 5 (20 mg, a yellow oil) in 24% yield.
