چکیده
In the title compound, C(15)H(19)Br(3)N(2)O(4)S, the thia-zine ring adopts a distorted half-chair conformation. The enolic H atom is involved in an intra-molecular O-H⋯O hydrogen bond, forming a six-membered ring. In the crystal, the mol-ecules are linked into a three-dimensional network through inter-molecular N-H⋯O, N-H⋯Br and O-H⋯Br hydrogen bonds.
