Procedure

To a solution of N-benzyl-3-hydroxy-5-iodo-benzamide (4.1 g) in a mixture of acetone and DMF (2:1, 100 mL) were added potassium carbonate (16.0 g) and 4-[3-(6-bromo-hexyl)-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (6.0 g). The resulting mixture was stirred at 75° C. for 2 days. Then the insoluble material was filtered out and the filtrate was diluted with ethyl acetate 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 8.7 g of yellow oil (100% yield).
