The asymmetric unit of the title compound, C(20)H(24)N(2)OS, consists of two crystallographically independent mol-ecules. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. The dihedral angles between the terminal benzene rings in the two mol-ecules are 75.52 (7) and 42.80 (7)°. In the crystal, inter-molecular N-H⋯S inter-actions link the mol-ecules into a chain along the c axis.
