Reaction Steps

The title compound was prepared from 2-[2-(4-fluoro-phenyl)-ethylsulfanyl]-3-[4-(2-hydroxy-ethyl)-phenyl]-propionic acid 2,2,2-trichloro-ethyl ester (34 mg, 0.072 mmol) and methanesulfonic acid (4-methanesulfonyloxy-phenyl)-acetic acid (15 mg, 0.065 mmol) in the same manner as described for example 1. The crude product was purified by HPLC (yield: 3.0 mg, 8.2%). 1H NMR (400 MHz, CDCl3): δ 7.17-7.24 (m, 4H), 7.00-7.10 (m, 6H), 6.89-6.93 (m, 2H), 4.26 (t, 2H), 3.80 (t, 2H), 3.46-3.50 (dd, 2H), 3.11 (s, 3H), 2.77-2.91 (m, 8H).
