In the title compound, C14H13N3O2S, the dihedral angle between the thio-phene and phenyl rings is 24.95 (8)°. The mol-ecular structure is consolidated by intra-molecular N-H⋯O and C-H⋯S inter-actions. The crystal structure features N-H⋯N and N-H⋯O hydrogen bonds forming centrosymmetric R 2 (2)(12) dimers, which are linked into a two-dimensional network parallel to (011) with an S(6)R 2 (2) S(6) motif. In addition, π-π stacking inter-actions [centroid-centroid distance = 3.7013 (12) Å] occur between the thio-phene and phenyl rings of adjacent mol-ecules.
