Tautomerism of Heterocyclic Compounds, IX. Preparation of Substituted Benzothiazines and Benzoxazines via N-AroylchloroformamidinesThe 2-aminobenzothiazinones 3a-c are prepared by reaction of 1a-c with phenylhydrazine. The aromatic 2-hydroxycarbonyl chlorides 4a, b react with 1-cyanopyrrolidine to give the not isolated heterocyclic compounds 5a, b which are readily hydrolized to 6a, b.
