The title compound was prepared from 2-[2-(4-fluoro-phenyl)-ethylsulfanyl]-3-(4-hydroxymethyl-phenyl)-propionic acid 2,2,2 trichloro-ethyl ester (675 mg, 1.45 mmol) and 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (410 mg, 1.59 mmol) in the same manner as described for 4-[2-[2-(4-fluoro-phenyl)-ethylsulfanyl]-2-(2,2,2-trichloro-ethoxy-carbonyl)-ethyl]-benzoic acid 2-phenyl-5-trifluoromethyl-oxazol-4-ylmethylester. The crude product was obtained as an oil which was carried on to the next step without further purification (892 mg, 79.4%). 1H NMR (500 MHz, CDCl3): δ 8.15 (d, 2H), 7.57 (d, 1H), 7.52 (t, 2H), 7.41 (d, 2H), 7.12 (t, 2H), 6.97 (t, 2H), 5.42 (s, 2H), 4.72 (q, 2H), 3.59 (dd, 1H), 3.25 (dd, 1H), 2.78-3.05 (m, 5H). Mass Spectrum: M+H+ 705.89.
