In the title compound, C(17)H(18)BrN(3)O(2)S, the dihedral angle between the aromatic rings is 9.15 (17)°. A bifurcated intra-molecular N-H⋯(N,O) hydrogen bond generates two S(5) rings and a weak intra-molecular C-H⋯S inter-action completes an S(6) ring motif. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R(2) (2)(8) loops and weak C-H⋯S and C-H⋯π inter-actions are also present.
