Versuchsvorschrift

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 (600 mg, 1.03 mmol), iodomethylcyclopentane (260 mg, 1.24 mmol), and potassium carbonate (356 mg, 2.57 mmol) to afford 4-[3-[6-(3-bromo-5-cyclopentylmethoxy-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (487 g, 73%) as a colorless viscous oil: EI(+)-LRMS m/e calcd for C35H49BrO7 (M+H)+ 663.45. found 663.5.
