چکیده
In the title compound, C(13)H(17)N(3)O(2), the mean plane of the cyclo-hexane ring forms a dihedral angle of 33.12 (5)° with the pyridine ring. The two O atoms are twisted away from each other, as indicated by the C-N-N-C torsion angle of -74.97 (9)°. In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds. The structure is also stabilized by C-H⋯π inter-actions.
