Reaction Steps

DMF (3 drops) was added to a mixture of 2-chloro-3-nitrobezoic acid (0.99 g, 4.9 mmol), oxalyl chloride (0.47 mL, 5.4 mmol) in CH2Cl2 (20 mL) at 25° C. stirring under N2. After gas formation ceased, all the solid went into solution. After 3 hours the solvent was removed under reduced pressure to leave a light yellow solid which was treated with cold NH4OH (20 mL). 2-Chloro-3-nitrobenzamide was collected as an off-white solid (1.02 g, 100%).
