In the title compound, C(10)H(12)N(2)OS, the amide NCO group is twisted relative to the thio-ureido SCN(2) group, forming a dihedral angle of 55.3 (2)°. The crystal packing shows inter-molecular N-H⋯S and weak C-H⋯O inter-actions, the former giving rise to the formation of centrosymmetric R(2) (2)(8) dimers.
