Reaction Steps

Dimethylformamide (0.6 ml) is added to a mixture of 2,3,4,5-tetrafluorobenzoic acid (100 g) and thionyl chloride (135 ml), and the mixture is heated under reflux with stirring for 7 hours. The reaction mixture is condensed under vacuum to yield crude 2,3,4,5-tetrafluorobenzoyl chloride as a pale yellow oily residue (110.5 g).
