The asymmetric unit of the title compound, C14H10Br2N6O, contains two crystallographically independent molecules. The pyrazole ring of one molecule makes dihedral angles of 22.0 (3) and 3.5 (3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other molecule are 9.2 (3) and 2.1 (3)°, respectively. The molecules are linked by N—H...O, C—H...N and C—H...Br hydrogen bonds.
