Versuchsvorschrift
A mixture of 2-chloro-4-fluoro-5-nitrobenzoic acid (50.0 g, 0.228 mol) and N,N-dimethylformamide (5 drops) in 1,2-dichloroethane is treated dropwise with oxalyl chloride (30.8 mL, 0.353 mol), refluxed for 3 hours, cooled, and concentrated in vacuo to obtain the title product as an orange solid which is identified by NMR spectral analysis.
