The title compound, C11H11N3, crystallizes with two molecules (A and B) in the asymmetric unit. The geometries of both molecules are very similar, with the exception of the torsion angles of the inter-ring chains; the values for C—N—C—C are 67.4 (5) and −69.3 (5)° for molecules A and B, respectively. The dihedral angles between the pyridyl ring planes are 84.0 (2) and 83.2 (2)° for molecules A and B, respectively. In the crystal, weak intermolecular N—H⋯N hydrogen bonds and C—H⋯π interactions contribute to the stabilization of the packing.
