Diethyl 4-(4-ethoxy­phen­yl)-2,6-dimethyl-1,4-dihydro­pyridine-3,5-dicarboxyl­ate

In the title compound, C(21)H(27)NO(5), 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)°. An intra­molecular C—H⋯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—H⋯O hydrogen bonds and the chains are inter­connected 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 inter­actions.
