Procedure

A mixture of N-[4-(ethoxycarbonylmethyl)phenyl]-3-(1,5-diphenyl-1H-pyrazol-4-yl)propionamide (0.76 g), a 1N aqueous sodium hydroxide solution (5 ml) and ethanol (5 ml) was stirred at 50° C. for 3 hrs. The reaction mixture was poured into a 1N aqueous hydrochloric acid solution and the precipitated crystals were collected by filtration, washed with water and dried to give (4-{[3-(1,5-diphenyl-1H-pyrazol-4-yl)propanoyl]amino}phenyl)acetic acid.
