In the title compound, C(18)H(17)N(5), the pyrrolidine ring adopts an envelope conformation. The pyrrolidine ring is disordered over two sets of sites with occupancy factors of 0.648 (6) and 0.352 (6). The dihedral angles between the pyrrolidine and pyridine rings are 14.6 (3)° for the major component and 16.2 (6)° for the ninor component. The crystal structure is stabilized by inter-molecular N-H⋯N and C-H⋯N inter-actions.
