Vorschrift

Chloroacetaldehyde diethyl acetal (1.9 g), potassium benzoate (2.0 g) and DMF (20 mL) were placed in a three-neck flask, followed by refluxing. Twenty hours later, the reaction mixture was cooled to room temperature, and water (60 mL) and ethyl acetate (80 mL) were added thereto, followed by stirring. After filtration and separation, the organic layer was concentrated and thereby yielded the target compound (0.69 g) in a yield of 30%.
