چکیده
In the title compound, C(21)H(27)NO(5), the dihydropyridine ring adopts a boat conformation. The ethoxy-phenyl ring is oriented approximately perpendicular to the planar part of the dihydropyridine ring, making a dihedral angle of 89.45 (6)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, neighbouring mol-ecules are linked into chains along the a axis by N-H⋯O hydrogen bonds and the chains are inter-connected into two-dimensional networks parallel to the ab plane by C-H⋯O hydrogen bonds. The structure is further stabilized by weak C-H⋯π inter-actions.
