Reaction Steps

4-[3-[6-(3-Benzylcarbamoyl-5-iodo-phenoxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy]-butyric acid ethyl ester (8.7 g) was dissolved in THF (30 mL) and 2 M NaOH was added (30 mL). The resulting heterogeneous mixture was stirred vigorously at 55° C. for 4 h. Then it was acidified with 3 N HCl and extracted into diethyl ether. Etherate extract was washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to produce 8.1 g (100% yield) of colorless oil which solidified upon standing.
