HCID 212519672-Amino-3-nitrobenzoyl chlorideYield 100%

Procedure

A mixture of 9.90 parts of 2-amino-3-nitrobenzoic acid and 32.4 parts of thionyl chloride was stirred for 15 min at reflux temperature under argon. The excess of thionyl chloride was evaporated, yielding 10.8 parts (100%) of 2-amino-3-nitrobenzoyl chloride (interm. 39).
