Procedure
tert-Butyl ((5-(2-fluorophenyl)-1-((3-hydroxyphenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 1h (100 mg, 0.22 mmol), methyl bromoacetate (40 mg, 0.26 mmol) and potassium carbonate (45 mg, 0.33 mmol) were added to 5 mL of acetonitrile, then the reaction solution was heated up to 50° C. and stirred for 16 h. The reaction solution was concentrated under reduced pressure. 50 mL of water were added, and the reaction solution was extracted with ethyl acetate (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 methyl 2-(3-((4-(((tert-butoxycarbonyl)(methyl)amino)methyl)-2-(2-fluorophenyl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)acetate 1i (110 mg, a yellow oil), which was used directly in the next step.
