実験手順

[6-(4-{1-Ethyl-1-[4-((E)-3-ethyl-3-hydroxy-1-pentenyl)-3-methyl-phenyl]-propyl}-2-methyl-phenyl)-pyridin-3-yl]-acetic acid ethyl ester (Example 81-(1); 24.6 mg, 0.047 mmol) was dissolved in methanol/tetrahydrofuran=1:1 (1 mL). A 1 N sodium hydroxide aqueous solution (0.1 mL) was added, and the mixture was stirred at room temperature for one hour. A 30% sodium dihydrogenphosphate aqueous solution (0.3 mL) was added to the reaction mixture, and then the reaction mixture was concentrated under reduced pressure. The residue was purified by preparative TLC (hexane/ethyl acetate=1/1) to give the title compound (15 mg, 65%).
