The molecular structure of the title compound, C(17)H(20)N(4)OS(2), does not show any intramolecular aromatic pi-pi interactions, but the crystal packing reveals the presence of intermolecular C--H...O and C-H...pi interactions. The C--H...O interactions generate chains of molecules that are linked into sheets by C-H.pi interactions about inversion centres.
