Procedure
A similar procedure as described in Example 43, step 4 was used, starting from 4-[3-[6-(3-benzyloxy-5-bromo-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (260 mg, 0.39 mmol), 3-fluoro-phenylboronic acid (109 mg, 0.78 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (73 mg, 0.1 mmol), and cesium carbonate (253 mg, 0.78 mmol) to obtain 4-[3-[6-(5-benzyloxy-3′-fluoro-biphenyl-3-yloxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (244 mg, 92%) as a colorless viscous oil: ES(+)-HRMS m/e calcd for C42H49FO7 (M+Na)+ 707.3354. found 707.3355.
