Procedure

Chloroacetaldehyde diethyl acetal (2.00 g), potassium benzoate (1.91 g), potassium iodide (0.41 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 (30 mL) and ethyl acetate (80 mL) were added thereto, followed by stirring. After filtration, the organic layer was separated, was subjected to vacuum concentration and then to Kugelrohr distillation at 110-120° C. and at 1 mmHg and thereby yielded the target compound (2.41 g) in a yield of 77%.
