The title compound, C20H18N6O5·0.5C3H7NO, crystallized as a dimethylformamide (DMF) solvate. In the main molecule, the dihedral angle between the pyridodipyrimidine fused-ring system and the benzamide substituent is 82.26 (11)°. In the crystal, the benzamide molecules are linked by N—H...O hydrogen bonds to generate tetramers with an approximate square-prismatic shape, which appears to correlate with the tetragonal crystal symmetry. The DMF molecule is disordered about a crystallographic twofold axis and accepts a C—H...O interaction from the benzamide molecule.
