Abstract: In the title molecule, C16H14N4O4, the quinazoline ring is substantially planar (r.m.s. deviation = 0.0129 Å) and forms a dihedral angle of 2.73 (8)° with the benzene ring. The conformation of the molecule is stabilized by an intramolecular C-H...N hydrogen bond. In the crystal, molecules are linked into chains running parallel to the b axis by C-H...O hydrogen bonds. In addition, [pi]-[pi] stacking is observed between dimethoxy-substituted and nitro-substituted benzene rings, with centroid-centroid distances in the range 3.6438 (10)-3.7148 (10) Å.
