Procedure

To 3-[1-(4-Carbamoyl-thiazol-2-yl)-5-(4-methoxy-phenyl)-1H-pyrrol-2-yl]-propionic acid ethyl ester (0.15 mmol) in a 2:1 mixture of methanol/THF was added 2M LiOH (0.30 mmol). The reaction mixture was stirred for 24 hours. The solvent was removed in vacuo. The residue was diluted with water (2 mL) and extracted with ethyl ether. The pH of the aqueous layer was adjusted to 2 with 1N HCl. The resulting suspension was filtered off; the solid was washed with water and dried to give the final compound. Yield: 36 mg, 69%.
