The mol-ecule of the title compound, C(11)H(14)N(2)O(3), adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the hydrazinecarboxyl-ate plane is 12.06 (9)°. Mol-ecules are linked into a one-dimensional network by N-H⋯O hydrogen bonds and C-H⋯π inter-actions. The benzene rings of inversion-related mol-ecules are stacked with their centroids separated by 3.777 (1) Å, indicating π-π inter-actions.
