In the title compound, C16H14N2O3S, the 1,3-benzoxazole ring system is essentially planar (r.m.s deviation = 0.004 angstrom) and makes a dihedral angle of 66.16 (17)degrees with the benzene ring of the methoxyphenyl group. Two intramolecular N -H center dot center dot center dot O and N -H center dot center dot center dot N hydrogen bonds occur, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C-H center dot center dot center dot O hydrogen bonds link the molecules into inversion dimers with R-2(2)(14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C-H center dot center dot center dot-pi and pi-pi-stacking interactions [centroid-to-centroid distances = 3.631 (2) and 3.631 (2) angstrom], 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 center dot center dot center dot H (39.3%), C center dot center dot center dot-H/H center dot center dot center dot C (18.0%), O center dot center dot center dot H/H center dot center dot center dot O (15.6) and S center dot center dot center dot H/H center dot center dot center dot S (10.2%) interactions.
