In the title compound, C(12)H(12)N(2)O, the dihedral angle between the planes of the pyridine and phenyl rings plane is 35.94 (12)°. In the crystal structure, centrosymmetrically related mol-ecules are linked by a pair of N-H⋯N hydrogen bonds, forming a dimer with an R(2) (2)(8) ring motif. In addition, there is an intra-molecular N-H⋯O inter-action.
