실험 절차

To a solution of 4-[3-[6-(3-acetyl-5-trifluoromethanesulfonyloxy-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (500 mg) in 1,2-dimethoxyethane (5 mL) were added 2,2-difluoro-benzo[1,3]dioxole-5-boronic acid (273 mg), 2 M aq. sodium carbonate solution (1.0 mL) and Pd(PPh3)4 (8 mg) and the resulting mixture was stirred at 90° C. for 3 h. Then the reaction mixture was diluted with ethyl acetate, filtered through Celite and washed with water and brine. The organic extract was dried over anhydrous sodium sulfate, concentrated and purified on a silica gel column using ethyl acetate and hexanes to yield 300 mg of the title compound (59% yield). HRMS calcd for C38H44O9F2 [M+Na]+ 705.2845, observed 705.2843.
