Procedure

After filling in a dry 250 ml flask respectively 59.89 g (0.271 mol) of 2,3-dichlorophenoxyacetic acid synthesized in Example 5 and 79.1 ml (1.084 mol) of thionyl chloride, the reaction mixture was then heated and refluxed for 4-5 hours. When treated as in Example 2 on completion of the reaction, 60.93 g of 2,3-dichlorophenoxyacetyl chloride was obtained as a raw reaction product.
