In the molecule of the title compound, C16H20N4, the 1,3-diazinane ring adopts a chair conformation and the dihedral angle formed by the pyridine rings is 78.64 (8)°. The molecular conformation is stabilized by an intramolecular C-H N hydrogen bond, forming an S(6) ring motif. In the crystal, centrosymmetrically related molecules are linked into dimers by pairs of N-H N hydrogen bonds, generating rings of R22(10) graph-set motif.
