実験手順

tert-Butyl ((1-((3-(2-amino-2-oxoethoxy)phenyl)sulfonyl)-5-(2-fluorophenyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 2a (100 mg, 0.19 mmol) was dissolved in 20 mL of dichloromethane. The reaction solution was cooled in an ice bath, 5 mL of trifluoroacetic acid were dropwise added, and then the reaction solution was stirred for 2 h. 50 mL of saturated sodium bicarbonate solution were added, and the reaction solution was extracted with dichloromethane (50 mL×3). 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 silica gel column chromatography with elution system A to obtain the title product 2-(3-((2-(2-fluorophenyl)-4-((methylamino)methyl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)acetamide 2 (60 mg, a yellow oil) in 75% yield.
