実験手順

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 4 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.
