Reaction Steps

3-[1-(4-carbamoyl-2-methyl-phenyl)-5-(4-methoxy-phenyl)-1H-pyrrol-2-yl]propanoic acid ethyl ester (86 mg, 0.216 mmol) was dissolved in ethanol (4 mL). Water (0.5 mL) was added to the ethanolic solution followed by the addition of 1N NaOH (0.51 mL, 0.51 mmol). The reaction mixture was stirred at room temperature for 1 h and then at 45° C. for an additional hour. After removal of the solvent in vacuo, the residue was diluted with water (6 mL) and extracted with ethyl acetate (2×6 mL). The pH of the aqueous layer was adjusted to 2 with 1 N HCl and then extracted with ethyl acetate (6 mL). The combined organic layer was dried over anhydrous Na2SO4 and the solvent removed in vacuo to obtain 3-[1-(4-Carbamoyl-2-methyl-phenyl)-5-(4-methoxy-phenyl)-1H-pyrrol-2-yl]-propanoic acid as the product (68 mg, 85%).
