Procedure
tert-Butyl ((5-(2-fluorophenyl)-1-((3-hydroxyphenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 1h (100 mg, 0.22 mmol) was dissolved in 20 mL of N,N-dimethylformamide, followed by addition of cesium carbonate (215 mg, 0.66 mmol) and 2-bromo-N-cyclopropyl-acetamide (61 mg, 0.34 mmol, prepared by a known method disclosed in “Journal of Medicinal Chemistry, 1987, 30(1), 20-24”) and then the reaction solution was stirred for 16 h. 50 mL of water 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 to obtain the title product tert-butyl ((1-((3-(2-(cyclopropylamino)-2-oxoethoxy)phenyl)sulfonyl)-5-(2-fluorophenyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 3a (100 mg, a yellow oil), which was used directly in the next step.
