In the title compound, C19H17NO5, the dihedral angle between the phenyl groups is 79.55 (15)degrees. The terminal ethoxy group is disordered over two orientations in a 0.873 (6):0.127 (6) ratio. In the crystal, molecules are linked by N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds into [001] chains which incorporate R-1(2) (6) loops. A very weak C-H center dot center dot center dot pi contact also occurs.
