Versuchsvorschrift

5N NaOH (0.5 mL) was added to a solution of 3-{4-[2-(2-Cyclohexyl-5-methyl-oxazol-4-yl)-ethoxy]-phenyl}-2-methyl-2-(3-thiophen-3-yl-phenoxy)-propionic acid ethyl ester and 3-{4-[2-(2-Cyclohexyl-5-methyl-oxazol-4-yl)-ethoxy]-phenyl}-2-methyl-2-phenoxy-propionic acid ethyl ester in ethanol (4 mL). The resultant mixture was refluxed under an atmosphere of nitrogen for 2 h, then cooled to ambient temperature. The reaction mixture was concentrated in vacuo, diluted with 1N HCl, and extracted with CH2Cl2. The organic layer was dried through a Varian ChemElut cartridge, concentrated in vacuo, and purified by LCMS. 1H NMR (400 MHz, CDCl3): δ 7.39-7.26 (m, 5H), 7.17 (d, 2H, J=8.60 Hz), 7.11-7.10 (m, 1H), 6.82-6.80 (m, 1H), 6.78 (d, 2H, J=8.60 Hz), 4.11 (t, 2H, J=6.26 Hz), 3.25 (d, 1H, J=14.08 Hz), 3.13 (d, 1H, J=14.08 Hz), 2.93 (t, 2H, J=6.26 Hz), 2.87-2.81 (m, 1H), 2.28 (s, 3H), 1.99 (d, 2H, J=12.51 Hz), 1.77 (d, 2H, J=12.51), 1.67 (d, 2H, J=12.51), 1.57-1.46 (m, 2H), 1.45 (s, 3H), 1.37-1.19 (m, 2H).
