Participants

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 (2.14 g, 4.53 mmol), 3-bromo-5-(propane-1-sulfonyl)-phenol (1.15 g, 4.12 mmol), and potassium carbonate (1.14 g, 8.24 mmol) to afford 4-[3-{6-[3-bromo-5-(propane-1-sulfonyl)-phenoxy]-hexyl}-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (2.67 g, 97%) as a colorless viscous oil: ES(+)-HRMS m/e calcd for C32H45BrO8S (M+Na)+ 691.1911, found 691.1905.
