Methyl 2-(4-meth-oxy-3-nitro-benzamido)-acetate.
The title compound, C(11)H(12)N(2)O(6), crystallizes with two independent mol-ecules in the asymmetric unit, which differ slightly in conformation. The dihedral angle between the amide O=C-N plane and the attached benzene ring is 19.5 (3)° in one mol-ecule and 23.4 (3)° in the other. In the crystal, the two independent mol-ecules are connected alternately by N-H⋯O hydrogen bonds, forming a chain along the a axis.
