Procedure
The title compound was prepared from 3-[3-(3-bromo-propoxy)-phenyl]-2-methoxy-propionic acid methyl ester (Example 323, Step 1) and 3-hydroxybenzoic acid methyl ester via the same procedure used for the preparation of (2S)-2-methoxy-3-[4-(3-phenoxy-propoxy)-phenyl]-propionic acid (Example 285, Step 1). The enatiomers were separated by chiral HPLC. MS (ES) for C20H22O7 [M+Na]+: 397.4.
