In the title compound, C20H18Br2N 4O8, the inter-planar angle of the pyrimidine rings is 75.1 (2)°. The central benzene ring is inclined at inter-planar angles of 66.5 (2) and 71.9 (2)° with respect to the two pyrimidine rings. In the crystal structure, adjacent molecules are connected into two-molecule-thick arrays parallel to the bc plane via short Br⋯Br [3.5328 (12) Å] and Br⋯O [3.206 (3) and 3.301 (4) Å] inter-actions. A weak inter-molecular π-π aromatic stacking inter-action [centroid-centroid distance = 3.526 (3) Å] is also observed.
