In the title compound, C(20)H(16)BrFN(4)O(3), the pyrimidine and 2-bromo-4-fluoro-phenyl rings are twisted away from the central benzene ring, making dihedral angles of 77.7 (1) and 85.5 (1), respectively. A pair of C-H⋯F inter-actions is involved in an R(2) (2)(8) motif, linking the mol-ecules into dimers. These ring motifs are situated about the crystallographic centres of symmetry. C-H⋯O hydrogen bonds link the dimers into chains running parallel to [11]. Additionally, a weak C-F⋯π-electron r ...[more]
