چکیده
The title compound, C(15)H(16)N(4)O, was prepared by the reaction of pyridine-3-carbaldehyde with 4-dimethyl-amino-benzo-hydrazide in methanol. The dihedral angle between the pyridine and the benzene rings is 5.1 (3)°. In the crystal structure, the hydrazone mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains along the b axis.
