In the racemic title compound, C19H14N2OS, the two phenyl substituents on the 1,3-thiazine ring are almost perpendicular to the pyridine ring which is fused to the thiazine ring [interring dihedral angles = 87.90 (8) and 85.54 (7)°]. The dihedral angle between the two phenyl rings is 75.11 (7)°. The sixmembered thiazine ring has an envelope conformation with the ortho-related C atom forming the flap. The crystals exhibit face-to-edge aromatic-ring interactions with the nearest C-H⋯C distance equal to 3.676 (3) Å.
