실험 절차

A mixture of 0.850 g of 1-(5-chloro-2,4-dihydroxy-3-propylphenyl)ethanone, 1.811 g of 4-[4-acetyl-3-[3-(3-bromopropoxy)propoxy]-2-propylphenoxy]butanoic acid ethyl ester and 1.0 g of anhydrous potassium carbonate in 65 ml of anhydrous acetone was stirred at reflux for 4 days. Additional 1.0 g portions of potassium carbonate were added after 21 and 30 hours. The reaction mixture was filtered and the filtrate was concentrated in vacuo to a brown oil. Purification by high pressure liquid chromatography using 20% ethyl acetate-hexane gave 0.516 g (22% yield) of 4-[4-acetyl-3-[3-[3-(4-acetyl-6-chloro-3-hydroxy-2-propylphenoxy)propoxy]propoxy]-2-propylphenoxy]butanoic acid ethyl ester as a yellow oil.
