Versuchsvorschrift

737 g (3.02 mols) of 2,3,4-trichloro-5-fluorobenzoic acid are introduced into 1.5 liters of thionyl chloride at room temperature, and the mixture is refluxed for 16 hours until the gas evolution ceases. Excess thionyl chloride is removed by distillation, and the residue is distilled.
