The asymmetric unit of the title compound, C(11)H(14)N(2)O(3), contains two independent mol-ecules with close conformations; the C=N-N-C torsion angle is 176.4 (1)° in both mol-ecules. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains running along the [01] direction.
