%X In the title compound, C21H27NO5, the dihydropyridine ring adopts a boat conformation. The ethoxyphenyl ring is oriented approximately perpendicular to the planar part of the dihydropyridine ring, making a dihedral angle of 89.45 (6)¡ã. An intramolecular C¡ªH...O hydrogen bond generates an S(6) ring motif. In the crystal structure, neighbouring molecules are linked into chains along the a axis by N¡ªH...O hydrogen bonds and the chains are interconnected into two-dimensional networks parallel to the ab plane by C¡ªH...O hydrogen bonds. The structure is further stabilized by weak C¡ªH...¦Ð interactions.
