Methyl 2-(3-((4-(((tert-butoxycarbonyl)(methyl)amino)methyl)-2-(2-fluorophenyl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)acetate 1i (110 mg, 0.20 mmol) was dissolved in 10 mL of a solution of methylamine in methanol (33%), and the reaction solution was heated up to 40° C. and stirred for 2 h. The reaction solution was concentrated under reduced pressure to obtain the title product tert-butyl ((5-(2-fluorophenyl)-1-((3-(2-(methylamino)-2-oxoethoxy)phenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 1j (60 mg, a yellow oil), which was used directly in the next step.
