In the title compound, C(15)H(19)N(3), the pyrimidine ring is approximately planar [maximum deviation = 0.007 (1) Å] and forms a dihedral angle of 3.15 (6)° with the benzene ring. In the crystal packing, inter-molecular N-H⋯N hydrogen bonds link pairs of neighbouring mol-ecules into dimers with R(2) (2)(8) ring motifs. These dimers are stacked along the b axis.

The conformation of the title mol-ecule, C(25)H(23)FN(4)O, is mainly determined by an intra-molecular N-H⋯N hydrogen bond closing a six-membered ring and the dihedral angles between the pyrimidine ring and the three benzene rings which are 12.8 (2), 12.0 (2) and 86.1 (2)°. An intra-molecular N-H⋯F inter-action also occurs. The crystal stucture is stabilized by weak C-H⋯O and C-H⋯π inter-actions...
