0.94 g (10 mmol) of phenol, 1.52 g (10 mmol) of chloroacetaldehyde diethyl acetal, 2.77 g (20 mmol) of potassium carbonate, 500 mg of potassium iodide and 5 ml of dimethylformamide were heated for 1 hour at 175° C. under microwave conditions. The mixture was then diluted with 2M aqueous sodium hydroxide solution and extracted with dichloromethane. The organic layer was dried with sodium sulfate and the solvent evaporated in vacuum. The crude product was obtained in almost quantitative yield.
