Abstract
In the title compound, C15H15N3OS, the dihedral angle between the planes of the benzene and pyridine rings is 26.86 (9)degrees. Intramolecular N-H center dot center dot center dot O and C-H center dot center dot center dot S hydrogen bonds both generate S(6) rings. The C=O and C=S bonds lie to opposite sides of the molecule. In the crystal, inversion dimers linked by pairs of N-H center dot center dot center dot S hydrogen bonds generate R-2(2)(8) loops.
