Participants

Reaction Steps

tert-Butyl ((5-(2-fluorophenyl)-1-((4-hydroxyphenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 4d (100 mg, 0.22 mmol), 1-(hydroxymethyl)-N-methyl cyclopropanecarboxamide 5c (47 mg, 0.33 mmol), diisopropyl azodicarboxylate (150 mg, 0.65 mmol) and triphenylphosphine (171 mg, 0.65 mmol) were added to 3 mL of dichloromethane and then the reaction solution was stirred for 16 h. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by thin layer chromatography with elution system B to obtain the title product tert-butyl ((5-(2-fluorophenyl)-1-((4-((1-(methylcarbamoyl)cyclopropyl)methoxy)phenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 6a (100 mg, a yellow oil) in 81% yield.
