実験手順

Ethyl 3-(3-tert-butyl-4-hydroxyphenyl)-2-ethoxypropanoate (0.15 g, 0.44 mmole) and 4-{2-[(methylsulfonyl)oxy]ethyl}phenyl methanesulfonate (0.26 g, 0.89 mmole) were dissolved in 2-butanone (4 ml). Polyethyleneglycol 400 (0.05 g) and anhydrous potassium carbonate (0.092 g, 0.67 mmole) were added the mixture. After stirring at reflux for 16 hours it was checked using HPLC whether all the starting material was consumed. The mixture was washed with water dried with magnesium sulfate and evaporated. Purification of the crude product with preparative HPLC (Kromasil C8, 7 μm, 50×250 mm) using actonitrile(40-80%) in ammonium acetate buffer (pH 7) as mobile phase gave 0.048 g (22% yield) of the desired product
