In the title compound, C(17)H(23)N(3)O(6), the two meth-oxy-carbonyl C-O-C=O planes are inclined at dihedral angles of 5.3 (4) and 83.9 (4)° with respect to the central pyridine ring. An intra-molecular N-H⋯O hydrogen bond generates an S(5) ring motif. In the crystal, mol-ecules are linked into a chain along the c axis via C-H⋯O hydrogen bonds.
