title: (E)-2-{1-[(6-Chloro-pyridin-3-yl)meth-yl]imidazolidin-2-yl-idene}-2-cyano-N-(2-methylphenyl)acetamide.
abstract: In the title compound, C(19)H(18)N(5)O, the imidazolidine ring makes dihedral angles of 87.62 (17) and 28.27 (11)° with the pyridine and benzene rings, respectively. An intra-molecular N-H⋯O hydrogen bond is observed between the carbonyl O atom and an imidazolidine H atom. In the crystal, an inter-molecular N-H⋯N hydrogen bond gives rise to a linear chain running along the b axis.
