The title compound was prepared from 3-(4-carboxymethyl-phenyl)-2-chloro-propionic acid 2,2,2-trichloro-ethyl ester (1.17 g, 3.13 mmol) and 2-(4-fluoro-phenyl)-ethanethiol (0.53 g, 3.44 mmol) as described for 3-[4-(tert-butyl-dimethyl-silanyloxy-methyl)-phenyl]-2-[2-(4-fluoro-phenyl)-ethylsulfanyl]-propionic acid methyl ester. After purification by flash chromatography with n-heptane/EtOAc 10:1 as the eluent the product was obtained as a solid (611 mg, 39.6%). 1H NMR (300 MHz, CDCl3): δ 7.09-7.23 (m, 6H), 6.94-6.99 (m, 2H), 4.65-4.77 (q, 2H), 3.56-3.61 (m, 3H), 3.18-3.28 (dd, 1H), 2.78-3.02 (m, 5H).
