Procedure

Under nitrogen, 2-methyl-2-(4-{2-[5-methyl-2-(4-pyrimidin-2-yl-phenyl)-oxazol-4-yl]-ethoxy}-phenoxy)-propionic acid ethyl ester (0.53 mmol) in ethanol (2.5 mL) and THF (2.5 mL) was treated with 2.0 N NaOH (2.0 mL). The reaction mixture was stirred at 55° C. for 1 h and concentrated in vacuo. The resulting slurry was suspended in ethyl acetate, acidified to pH 1 with 1N HCl, and partitioned. The organic layer was washed with brine, dried (Na2SO4), and concentrated in vacuo to yield the desired product. 1H NMR (400 MHz, CDCl3) δ8.76 (d, 1 H), 8.45 (d, 2 H), 8.06 (d, 2 H), 7.15 (t, 2 H), 6.76 (d, 2 H), 6.71 (d, 2 H), 4.14 (t, 2 H), 2.93 (t, 2 H), 2.33 (s, 3 H), 1.45 (s, 6 H); MS (EI) 460.3 (M+H)+.
