Abstract
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)degrees with respect to the central pyridine ring. An intramolecular N-H center dot center dot center dot 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 center dot center dot center dot O hydrogen bonds.
