In the title mol-ecule, C19H23NO5, the dihedral angle formed by the benzene ring and the planar part of the dihydro-pyridine ring is 83.52 (5)°. The dihydro-pyridine ring adopts a flattened boat conformation. In the crystal, molecules are linked by N - H⋯O hydrogen bonds, generating chains running parallel to [100]. The crystal structure is consolidated by C - H⋯O contacts. © Fun et al. 2009.
