A mixture of 2-methyl-2-(4-{3-[3-methyl-2-oxo-1-(4-trifluoromethyl-benzyl)-imidazolidin-4-yl]-propyl}-phenoxy)-pentanoic acid ethyl ester (0.020 g, 0.040 mmol) and 5 N NaOH (0.5 mL) in EtOH (6 mL) was heated at reflux for 1 h. The reaction mixture was cooled and quenched with 1 N HCl. The mixture was then diluted with water and extracted with CH2Cl2. The organic layer was dried (Na2SO4) and the solvent removed in vacuo to afford 0.010 g (53%) 2-methyl-2-(4-{3-[3-methyl-2-oxo-1-(4-trifluoromethyl-benzyl)-imidazolidin-4-yl]-propyl}-phenoxy)-pentanoic acid. 1H NMR. HRMS (ES+) m/z exact mass calcd for C27H34N2O4F3 [M+1] 507.2471, found 507.2459.
