Procedure
100.00 g (0.50 mol) of 5-chloro-2-nitrobenzoic acid were mixed with 72.20 g (0.61 mol) of thionyl chloride and the mixture was heated under reflux for 2 h. The excess thionyl chloride was removed in vacuo. 106.50 g (ca. 98%) of crude 5-chloro-2-nitro-benzoyl chloride were obtained as an oil.
