Procedure

A mixture of 3.3 g (0.012 mole) of (4-acetyl-3-hydroxy-2-propylphenoxy)acetic acid ethyl ester, 18.0 g (0.059) of triethyleneglycol dimesylate and 3.3 g (0.024 mole) of anhydrous potassium carbonate in 100 ml of anhydrous acetone and 45 ml of anhydrous dimethylformamide was stirred at reflux for 26 hours. The reaction mixture was concentrated in vacuo to yield an oil which was dissolved in 60% ethyl acetate-toluene and passed through a column of 60 g of silica gel. The eluent was concentrated in vacuo and purified by HPLC using 35% ethyl acetate-toluene to give 3.06 g (53% yield) of [4-acetyl-3-[2-[2-[2-[(methylsulfonyl)oxy]ethoxy]ethoxy]ethoxy]-2-propylphenoxy]acetic acid ethyl ester as an oil.
