Reaction Steps
A slurry of 20 g (99 mmol) of 2-chloro-3-nitrobenzoic acid in 800 mL dichloromethane was cooled in an ice bath. Dimethylformamide (0.40 ml) was added to the reaction mixture followed by dropwise addition of 13.85 g (109 mmol) of oxalyl chloride. The reaction was allowed to warm to room temperature and was stirred for 6 h. Methanol (200 mL) was added dropwise and the reaction was stirred overnight. The solvent was evaporated in vacuo. The residue was triturated with n-hexane. The resulting solid was collected by filtration, washed with hexane and dried in vacuo to give 21.0 g (98%) of the title compound.
