Procedure
A solution of 40 ml (224 mmol) of ethyl diethoxyacetate, 19 ml (268 mmol) of acetyl chloride and 0.1 g (0.45 mmol) of iodine is heated at 50° C. for 4 hours. Only 60% of the desired product is formed. The reaction medium is cooled to room temperature, 19 ml (268 mmol) of acetyl chloride are added and the medium is heated at 50° C. for a further 18 hours. The reaction medium is evaporated to dryness under vacuum. 36.3 g (100%) of crude ethyl chloroethoxyacetate are obtained.
