Reaction Steps

4-(2-(3-Ethoxy-3-oxopropyl)-5-(4-methoxyphenyl)-1H-pyrrol-1-yl)-3-methylbenzoic acid (44 mg) was treated with TBTU (42 mg), DPPA (10 μL) and dimethylamine HCl (14 mg) in DCM (4 mL) over 8 h at room temperature. The reaction mixture was diluted with EtOAc (15 mL), washed with 0.5 N HCl (8 mL), saturated NaHCO3 (8 mL), and Brine (8 mL). After removal of solvents, the residue was purified by flash silcal gel chromatography to afford ethyl 3-(5-(4-methoxyphenyl)-1-(2-methyl-4-(methylcarbamoyl)phenyl)-1H-pyrrol-2-yl)propanoate (25 mg).
