Reaction Steps
A mixture of 4.0 g (0.012 mole) of 6-(4-acetyl-3-hydroxy-2-propylphenoxy)hexanoic acid methyl ester, 16.3 g (0.062 mole) of diethyleneglycol dimesylate and 3.4 g (0.024 mole) of anhydrous potassium carbonate in 90 ml of anhydrous acetone and 40 ml of anhydrous dimethylformamide was stirred at reflux for 22 hours. The solvents were removed in vacuo and the residue was treated with 100 ml of 50% ethyl acetate-hexane. Some of the residual starting dimesylate was insoluble and was removed by filtration. The filtrate was concentrated in vacuo and the residual oil was purified by HPLC to give 4.8 g (80% yield) of 6-[4-acetyl-3-[2-[2-[(methylsulfonyl)oxy]ethoxy]ethoxy]-2-propylphenoxy]hexanoic acid methyl ester as an oil.
