実験手順

A similar procedure as described in Example 43, step 3 was used, starting from 4-[3-[6-(3-bromo-5-hydroxy-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (930 mg, 1.6 mmol), benzyl bromide (343 mg, 2.0 mmol), and potassium carbonate (553 mg, 4.0 mmol) to afford 4-[3-[6-(3-benzyloxy-5-bromo-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (1.06 g, 98%) as a colorless viscous oil: ES(+)-HRMS m/e calcd for C36H45BrO7 (M+Na)+ 691.2241. found 691.2238.
