Abstract: In the molecule of the title compound, C19H18N4O3S, the central heterocylic ring system is oriented with respect to the trimethoxyphenyl and 4-methylphenyl rings at dihedral angles of 1.1 (5) and 15.1 (5)°, respectively. The dihedral angle between the two benzene rings is 16.1 (4)°. In the crystal structure, molecules are linked by intermolecular C-HO hydrogen bonds, and an intramolecular C-HN interaction also occurs.
