Abstract
In the title compound, C19H23N3OS, the oxadiazole and benzene rings are inclined at a dihedral angle of 50.30 (11)degrees, with the major twist between them occurring at the ring-methylene N-C bond [N-N-C-N torsion angle = -101.2 (2)degrees]. In the crystal, helical supramolecular chains along [010] are sustained by N-H center dot center dot center dot S hydrogen bonds. These are linked into layers lying parallel to (101) by methylene-phenyl C-H center dot center dot center dot pi interactions.
