Abstract: The asymmetric unit of the title compound, C₂₃H₂₃ClN₄OS, contains two crystallographically independent molecules in which the orientations of the propylamine group and chlorophenyl rings with respect to the fused ring system are different. The terminal cyclohexene ring adopts a half-chair conformation. The crystal packing is stabilized by N-HO, N-HN and C-HO hydrogen bonds and - interactions.
