Versuchsvorschrift

A mixture of 4.0 g of 4-(4-acetyl-3-hydroxy-2-propylphenoxy)butanoic acid ethyl ester, 19.9 g of triethylene glycol dimesylate and 3.6 g of anhydrous potassium carbonate in 80 ml of anhydrous acetone and 40 ml of anhydrous dimethylformamide was stirred at reflux for 23 hours. The reaction mixture was filtered and the filtrate was concentrated in vacuo to an oil which was purified by high pressure liquid chromatography using 30% ethyl acetate-toluene to give 3.0 g (45% yield) of 4-[4-acetyl-3-[2-[2-[2-[(methylsulfonyl)oxy]ethoxy]ethoxy]ethoxy]-2-propylphenoxy]butanoic acid ethyl ester as an oil.
