Reaktionsschritte

84 g of 2,4-dichloro-5-fluoro-benzoyl chloride are added dropwise to 250 ml of anhydrous ethanol at 50° to 60° C., the temperature being maintained by occasional cooling with ice-water. The mixture is then refluxed for about a further hour, the excess alcohol is distilled off and the residue is fractionated in vacuo. 84.9 g (~97%) of ethyl 2,4-dichloro-5-fluoro-benzoate are obtained at 132°-135° C./8 mbar.
