In the title compound, C17H23N3O6, the two methoxycarbonyl 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 intramolecular N—H⋯O hydrogen bond generates an S(5) ring motif. In the crystal, molecules are linked into a chain along the c axis via C—H⋯O hydrogen bonds.
