In the title compound, CHNOS, the 1,3-benzoxazole ring system is essentially planar (r.m.s deviation = 0.004 Å) and makes a dihedral angle of 66.16 (17)° with the benzene ring of the meth-oxy-phenyl group. Two intra-molecular N-H⋯O and N-H⋯N hydrogen bonds occur, forming (5) and (7) ring motifs, respectively. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into inversion dimers with (14) ring motifs, stacked along the -axis direction. The inversion dimers are linked by C-H⋯π and π-π-stacking inter-actions [centroid-to-centroid distances = 3.631 (2) and 3.631 (2) Å], forming a three-dimensional network. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from H⋯H (39.3%), C⋯H/H⋯C (18.0%), O⋯H/H⋯O (15.6) and S⋯H/H⋯S (10.2%) inter-actions.
