Procedure

The title compound was prepared by the same method as 4-{3-[6-(5-dimethylcarbamoyl-3′,4′-difluoro-biphenyl-3-yloxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy}-butyric acid ethyl ester starting from 4-[3-{6-[3-bromo-5-(3,3-difluoro-pyrrolidine-1-carbonyl)-phenoxy]-hexyl}-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (150 mg, 0.215 mmol), 3,4-methylenedioxyphenylboronic acid (73.56 mg, 0.43 mmol), PdCl2(dppf) (23.6 mg, 0.03 mmol) and cesium carbonate (141.5 mg, 0.43 mmol) in 1,2-dimethoxyethane (5.0 mL) to obtain 4-[3-{6-[3-benzo[1,3]dioxol-5-yl-5-(3,3-difluoro-pyrrolidine-1-carbonyl)-phenoxy]-hexyl}-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (127 mg, 80%) as a colorless oil
