Reaction Steps
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), 3,4-methylenedioxyphenylboronic acid (127 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-(3-benzo[1,3]dioxol-5-yl-5-benzyloxy-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (260 mg, 94%) as a colorless viscous oil: ES(+)-HRMS m/e calcd for C43H50O9 (M+Na)+ 733.3347. found 733.3345.
