Versuchsvorschrift

A similar procedure as described in Example 43, step 3 was used, starting from 4-[3-(6-bromo-hexyl)-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (8.07 g, 17.13 mmol), 3-bromo-5-ethoxy-phenol (3.38 g, 15.57 mmol), and potassium carbonate (4.3 g, 31.14 mmol) to obtain 4-[3-[6-(3-bromo-5-ethoxy-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (7.77 g, 82%) as a colorless oil: ES(+)-HRMS m/e calcd for C31H43BrO7 (M+H)+ 607.2265. found 607.2270.
