Abstract
In the title compound, C19H19NOS, the six-membered heterocyclic ring of the benzothiazine fragment exhibits a screw boat conformation. The plane of the fused benzene ring makes a dihedral angle of 72.38 (12)° with that of the terminal phenyl ring, and is nearly perpendicular to the mean plane formed by the atoms through the n-butyl chain, as indicated by the dihedral angle of 88.1 (2)°. In the crystal, molecules are linked by C—H⋯O interactions to form supramolecular chains along [110].
