title: (RS)-(2-Bromo-4-fluoro-anilino)[2-(4,6-dimethoxy-pyrimidin-2-yl-oxy)phen-yl]acetonitrile.
abstract: 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 ring inter-action was observed in the crystal packing [F⋯Cg = 3.459 (4) Å; Cg is the centroid of the pyrimidine ring]. There is also an intra-molecular N-H⋯Br inter-action in the structure.
