In the title compound, C(20)H(18)N(4)O(2), the amino-acrylamide group makes a dihedral angles of 4.0 (1)° with the amino-bound pyridyl ring and 15.66 (12)° with the amide-bound pyridyl ring. The dihedral angle between the amino-acrylamide group and the pendant 4-methoxy-phenyl group is 71.22 (9)°. In the crystal structure, N-H⋯N hydrogen bonds and C-H⋯O and C-H⋯N inter-actions help to establish the packing. Intra-molecular C-H⋯O and C-H⋯(N,O) contacts also occur.
