title: Ethyl 6-amino-8-(4-chloro-phen-yl)-9-nitro-2,3,4,8-tetra-hydro-pyrido[2,1-b][1,3]thia-zine-7-carboxyl-ate.
abstract: In the structure of the title compound, C(17)H(18)ClN(3)O(4)S, the thia-zinane ring displays a twist-boat conformation. The 1,4-dihydro-pyridine ring is approximately perpendicular to the benzene ring [dihedral angle = 88.3 (1)°]. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O inter-actions into a C(8) chain along [100].
