Versuchsvorschrift

3-(4-Bromophenoxy)-2-methylpropane-1,2-diol (261 mg, 1.00 mmol), acetone (10 mL), and a boron trifluoride diethyl ether complex (3 drops) were mixed. The mixture was then stirred at room temperature for 14 hours. A residue was obtained by concentrating the mixture under reduced pressure, and ethyl acetate and water were added thereto, followed by extraction. The organic layer was washed with a saline solution twice. A residue was obtained by concentrating the organic layer under reduced pressure, and the resulting residue was then subjected to chromatography refining (methylene chloride) using silica gel, obtaining 183 mg of the objective compound (yield: 61%).
