Reaction Steps

A similar procedure as described in Example 40, step 6 was used, starting from 4-[3-(6-bromo-hexyl)-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (1.13 g, 2.39 mmol), 3-bromo-5-ethanesulfonyl-phenol (576 mg, 2.17 mmol), and potassium carbonate (600 mg, 4.34 mmol) to afford 4-[3-[6-(3-bromo-5-ethanesulfonyl-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (1.35 g, 95%) as a colorless viscous oil: ES(+)-HRMS m/e calcd for C31H43BrO8S (M+Na)+ 677.1754, found 677.1756.
