title: 3-(2-Pyrid-yl)-N-p-tolyl-indolizin-1-amine.
abstract: In the title compound, C(20)H(17)N(3), there are four mol-ecules in the asymmetric unit. The dihedral angles between the indolizine ring system and the pyridyl ring are 6.6 (2), 7.4 (1), 4.0 (1) and 10.1 (4) in the four molecules. There are no further important differences between the independent molecules. In each molecule, there is an intra-molecular C-H⋯N hydrogen bond. The whole structure is stabilized by N-H⋯π and C-H⋯π inter-actions.
