Versuchsvorschrift

The commercially available sodium salt of 2-amino-5-nitro-benzenesulfonic acid can be converted to the corresponding sulfonyl chloride with phosphoryl chloride in the presence of a suitable co-solvent, such as sulfolane. Treatment with ammonia, e.g., ammonia solution in methanol or ammonia gas, affords the desired 2-amino-5-nitro-benzenesulfonamide intermediate.
