실험 절차

To a solution of 4-[3-{6-[3-(2,2-difluoro-benzo[1,3]dioxol-5-yl)-5-methanesulfonyl-phenoxy]-hexyl}-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (1.0 g) in ethanol (8 mL) was added a solution of NaOH (556 mg) in water (4 mL) and the resulting mixture was stirred at room temperature for 3 h. Then the reaction mixture was diluted with water, acidified with 3 N HCl and extracted into ethyl acetate. The organic extract was washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give an oil which was crystallized from ethyl acetate/hexanes mixture to yield the title compound (0.8 g, 87% yield). HRMS calcd for C33H36O10F2S [M+Na]+ 685.1889, observed 685.1892.
