The title compound, C(11)H(14)N(2)O(4), crystallizes with two independent but essentially identical mol-ecules in the asymmetric unit. Each mol-ecule adopts a trans configuration with respect to the C=N bond. Mol-ecules are linked into a one-dimensional network by inter- and intra-molecular N-H⋯O and C-H⋯O hydrogen bonds.
