In the title compound, C11H9NOS, the six-membered heterocycle of the benzo-thia-zine fragment exhibits a screw-boat conformation. The benzene ring makes a dihedral angle of 79.4 (1)° with the mean plane through the prop-2-ynyl chain and the ring N atom. In the crystal, mol-ecules are linked by C-H⋯O inter-actions of the acetyl-enic C-H group towards the carbonyl O atom of a neighbouring mol-ecule, forming zigzag chains running along the b-axis direction.
在标题化合物C₁₁H₉NOS中，苯并噻嗪片段的六元杂环呈扭曲船式构象。苯环与通过丙-2-炔基链和环N原子的平均平面形成79.4 (1)°的二面角。在晶体中，分子通过炔氢C-H基团与相邻分子的羰基O原子之间的C-H⋯O相互作用相连，形成沿b轴方向延伸的锯齿链。
