Abstract

In the title compound, C10H13N5, the piperidine ring adopts a chair conformation with the exocyclic N—C bond in an axial orientation, and the dihedral angle between the mean planes of piperidine and pyrimidine rings is 49.57 (11)°. A short intramolecular C—H...N contact generates an S(7) ring. In the crystal, N—H...N hydrogen bonds link the molecules into (100) sheets and a weak aromatic π-π stacking interaction is observed [centroid–centroid separation = 3.5559 (11) Å] between inversion-related pyrimidine rings.
