Methyl 2-methyl-7-oxo-1,2,4-triazolo[3,2-b]-1,3-thiazine-5-carboxylate
Abstract
In the title molecule, C8H7N3O3S, the triazole and thiazine rings are nearly coplanar, with a dihedral angle of 2.27 (9)°. The methyl carboxylate moiety is also planar and makes a dihedral angle of 7.31 (13)° with the thiazine–triazole mean plane.
