N-[2-(Amino-carbon-yl)phen-yl]-4-hydr-oxy-2-methyl-2H-1, 2-benzothia-zine-3-carboxamide 1,1-dioxide

Abstract

In the title compound, C17H15N3O5S, the thia-zine ring adopts a distorted half-chair conformation. The mol-ecular structure is stabilized by intra-molecular N- H⋯O, N- H⋯N and O- H⋯O hydrogen bonding. Pairs of mol-ecules are bound together as centrosymmetric dimers through N- H⋯O hydrogen bonds.
