In the title compound, C(19)H(17)NO(5), the dihedral angle between the phenyl groups is 79.55 (15)°. The terminal eth-oxy group is disordered over two orientations in a 0.873 (6):0.127 (6) ratio. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds into [001] chains which incorporate R(1) (2)(6) loops. A very weak C-H⋯π contact also occurs.
