چکیده
In the title compound, C(18)H(21)NO(5), the dihydro-pyridine ring adopts a flattened-boat conformation and its planar part forms a dihedral angle of 84.60 (2)° with the benzene ring. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds result in the formation of zigzag layers parallel to (001). These layers are inter-connected via C-H⋯π inter-actions.
