Abstract
In the title compound, C(13)H(10)BrN(3)O(3), the pyrimidine and benzene rings are twisted with an inter-planar angle of 58.4 (1)°. The secondary amide group adopts a cis conformation with an H-N-C-O torsion angle of 14.8 (1)°. In the crystal, mol-ecules are connected into inversion dimers via pairs of N-H⋯N hydrogen bonds, generating an R(2) (2)(8) motif. The dimers are further connected through a C-Br⋯O inter-action [3.136 (1) Å and 169.31 (1)°] into a chain along [110]. Weak C-H⋯N hydrogen bonds between the methyl benzoate groups and pyrimidine rings are also observed in the crystal structure.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
