Procedure

A mixture of ethyl 4-(6-acetyl-3-mercapto-2-propylphenoxy)-butyrate (2.0 g), (4-(3-bromopropylthio)-2-hydroxy-3-propylphenyl)ethanone (2.0 g), potassium iodide (0.5 g) and potassium carbonate (1.7 g) in acetone (40 ml) was heated with refluxing and stirring for 9 hours. After cooled, inorganic materials were separated by filtration and the filtrate was concentrated. The resultant residue was separated, and was purified through silicagel column chromatography (eluting with benzene:ethyl acetate=9:1) to give the title compound (1.8 g, 50.8%) as yellow oil.
