Procedure

A similar procedure as described in Example 43, step 4 was used, starting from 4-[3-[6-(3-acetyl-5-bromo-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (303 mg, 0.5 mmol), 3-fluoro-phenylboronic acid (140 mg, 1.0 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (73 mg, 0.1 mmol), and cesium carbonate (326 mg, 1.0 mmol) to obtain 4-[3-[6-(5-acetyl-3′-fluoro-biphenyl-3-yloxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (288 mg, 93%) as a colorless oil: ES(+)-HRMS m/e calcd for C37H45FO7 (M+Na)+ 643.3041. found 643.3039.
