Di-tert-butylphenyliodonium chloride (443 mg; 1 mmol), ethyl orthoacetate (342 mg; 2 mmol), and pentafluorobenzenesulfonic acid (298 mg; 1.2 mmol) were dissolved in chloroform (5 ml), and the resultant mixture was refluxed for 2 hours while being stirred. The solvent was removed through distillation, and the thus-obtained solid matter was washed with ether, to thereby yield 436 mg of the target compound as white crystals (yield: 68%).
