The asymmetric unit of the title compound, C17H20N4S, contains two independent molecules, the main difference between them being the dihedral angles between the benzene rings [19.99 (17) and 9.72 (17)°]. The molecules both have a trans conformation about the C=N double bond and intramolecular C—HS and N—HN hydrogen bonds are observed in both molecules. In the crystal, molecules are linked by weak N—HS hydrogen bonds with graph-set motif R22(8). In each molecule, all but one of the N atoms and both the S atoms are involved in hydrogen bonding.
