To a solution of 1-(4-(2,2-diethoxyethoxy)phenyl)ethanone (2.46 g, 7.34 mmol) in toluene (25 mL), was added PPA (2.50 g) and refluxed for 1 hour. Under ice-cold conditions, the reaction solution was added water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and the title compound (44 mg (yield 3.7%)) was obtained as a white solid.
