Reaction Steps
A similar procedure as described in Example 44, step 3 was used, starting from 4-[3-[6-(3-bromo-5-ethoxy-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (305 mg, 0.5 mmol), 5-indolineboronic acid (170 mg, 1.0 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (55 mg, 0.075 mmol), and cesium carbonate (331 mg, 1.0 mmol) to obtain 4-[2-(2-ethoxycarbonyl-ethyl)-3-{6-[3-ethoxy-5-(1H-indol-5-yl)-phenoxy]-hexyl}-phenoxy]-butyric acid ethyl ester (25 mg, 8%) as a light yellow oil: ES(+)-HRMS m/e calcd for C39H49NO7 (M+Na)+ 666.3401. found 666.3399.
