Versuchsvorschrift

To a stirring mixture of ethyl 4-(6-acetyl-3-hydroxy-2-propylphenoxy)butyrate (1.6 g), potassium iodide (0.5 g) and potassium carbonate (1.45 g) in acetone (30 ml) was added a solution of [4-(3-bromopropylthio)-2-hydroxy-3-propylphenyl]ethanone (1.9 g) in acetone (10 ml) dropwise with heating to reflux. After heating and refluxing with stirring for six hours, inorganic materials were separated by filtration and the filtrate was concentrated. The residue was separated and purified through silica-gel column chromatography (eluting with benzene:ethyl acetate=9:1) to give the title compound as crude crystals (2.1 g, 72.4%). This crystal was recrystallized from ethanol to colorless crystals, mp 65-66° C.
