The title compound was prepared from 2-chloro-3-[4-(3-hydroxy-propyl)-phenyl]-propionic acid 2,2,2-trichloro-ethyl ester (0.74 g, 1.98 mmol) and 2-(4-fluoro-phenyl)-ethanethiol (0.34 g, 2.17 mmol) as described for 3-[4-(tert-butyl-dimethyl-silanyloxy-methyl)-phenyl]-2-[2-(4-fluoro-phenyl)-ethylsulfanyl]-propionic acid methyl ester. After repeated purification by flash chromatography with n-heptane/EtOAc 9:1 as the eluent the product was obtained as an oil (94 mg, 9.6%). 1H NMR (300 MHz, CDCl3): δ 7.10-7.11 (m, 6H), 6.94-6.98 (t, 2H), 4.65-4.75 (q, 2H), 3.64-3.68 (t, 2H), 3.58-3.61 (dd, 2H), 3.17-3.23 (dd, 2H), 2.80-2.97 (m, 5H), 2.65-2.70 (t, 2H), 1.86-1.89 (m, 2H).
