N-(2,3-Dimethylphenyl)-4-hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide

In the crystal structure of the title compound, C18H18N2O4S, the thiazine ring adopts a distorted half-chair conformation. 1,2-Benzothiazines of this kind have a wide range of biological activities and are mainly used as medicines in the treatment of inflammation and rheumatoid arthritis. The enolic...
