In the title compound, C(16)H(20)N(2)O(6), two intra-molecular N-H⋯O hydrogen bonds occur, in which the carbonyl O atoms of the ethyl acetate groups serve as the acceptor atoms; both motifs generate S(6) rings. In the crystal, mol-ecules are linked by weak C-H⋯O links (with the acceptor O atoms part of the amide groups), generating [001] chains.
