Preparation of some 4‐hydroxyl‐1‐methyl‐1H‐2,1‐benzothiazine‐3‐carboxanilide 2,2‐dioxides

Journal of Heterocyclic Chemistry, 1972
AbstractAn improved, 3‐step synthesis of 3,4‐dihydro‐1‐methyl‐1H‐2,1‐benzothiazin‐4‐one 2,2‐dioxide has been developed. This general method offers a more facile entrance into the 2,1‐benzothiazine 2,2‐dioxide heterocyclic system than was heretofore available.
