実験手順

A mixture of 2.62 g of 1-(2,4-dihydroxy-3-propylphenyl)ethanone, 6.00 g of 6-[4-acetyl-3-(3-bromopropoxy)-2-propylphenoxy]hexanoic acid methyl ester and 3.70 g of anhydrous potassium carbonate in 100 ml of anhydrous acetone and 50 ml of anhydrous dimethylformamide was stirred at reflux for 20 hours. The reaction mixture was concentrated in vacuo and the residue was purified by liquid chromatography using 30% ethyl acetate-hexane to give 5.10 g (68% yield) of 6-[4-acetyl-3-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)propoxy]-2-propylphenoxy]hexanoic acid methyl ester as an oil.
