Procedure
A solution of 3-{4-[2-(1-Benzyl-3-methyl-2-oxo-imidazolidin-4-yl)-ethoxy]-phenyl}-2-(2-fluoro-phenoxy)-2-methyl-propionic acid ethyl ester and 5N NaOH (0.2 mL) in ethanol (2 mL) is refluxed under nitrogen for 1 h, cooled to ambient temperature, and concentrated in vacuo. The residue is diluted with 1N HCl, extracted with CH2Cl2, dried, concentrated, and purified by LCMS to provide the title compound. 1H NMR (400 MHz, CDCl3): δ 7.55 (d, 1H, J=8.4 Hz), 7.34-7.21 (m, 6H), 7.10-7.01 (m, 4H), 6.74 (d, 2H, J=8.4 Hz), 4.46-3.36 (m, 2H), 3.96 (q, 2H, J=6.0 Hz), 3.74-3.65 (m, 1H), 3.45-3.39 (m, 1H), 3.28, 3.16 (ABq, 2H, J=14.7 Hz), 3.05 (q, 1H, J=8.6 Hz), 2.26-2.19 (m, 1H), 1.93-1.86 (m, 1H), 1.41 (s, 3H). MS [ES+] m/z exact mass calcd for C29H32N2O5F 507.2295, found 507.2308.
