Reaction Steps

2-[5-[4-[(6-Hydroxy-2-(4-hydroxyphenyl)benzo[b]-thiophen-3-yl)carbonyl]-phenoxy]pentyl]-2-(4,4,5,5,5-pentafluoropentyl)malonic acid (1.1 g, 1.58 mmol) was dissolved in dimethyl sulfoxide (10 ml) and stirred for 3 hours at 120° C. The reaction mixture was cooled to room temperature, diluted with water, and then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane=1/1) to give 2-[5-[4-[(6-hydroxy-2-(4-hydroxyphenyl)benzo[b]thiophen-3-yl)carbonyl]phenoxy]-pentyl]-6,6,7,7,7-pentafluoroheptanoic acid (732 mg, Yield 71%) as a yellow solid.
