Abstract: The asymmetric unit of the title compound, C22H23N5O2, contains two independent molecules with similar conformations; the terminal pyridine rings are oriented at dihedral angles of 23.99 (8) and 18.07 (8)° with respect to the central benzene ring in one molecule and 28.99 (8) and 23.22 (8)° in the other. In the crystal, N-H...O and weak C-H...O hydrogen bonds link the molecules into a three-dimensional supramolecular structure. Weak intermolecular C-H...[pi] interactions are also observed in the crystal.
