Benzazoles: III. Synthesis and Transformation of 6-Chlorosulfonylbenzothiazolin-2-ones
The corresponding 6-chlorosulfonyl derivatives were synthesized from benzothiazolin-2-one and its 3-methylsubstituted by treatment with chlorosulfonic acid. By the action of water, alcohols and other nucleophilic agents (aliphatic and heterocyclic amines) on the obtained compounds, 2-oxobenzothiazoline-6-sulfonic acids, their esters and amides are obtained.
