Versuchsvorschrift
One drop of N,N-dimethylformamide was added to a thionyl chloride (2.03 g) suspension of 3-(chlorosulfonyl)-5-fluorobenzoic acid (1.36 g), followed by stirring at 75° C. for 1 hour. The solvent was evaporated, and this was azeotroped with toluene to obtain 3-(chlorosulfonyl)-5-fluorobenzoyl chloride (1.47 g).
