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

In the title compound, C₂₀H₂₅NO₅, the di­hydro­pyridine ring adopts a flattened boat conformation. The meth­oxy­phenyl ring is almost perpendicular to the mean plane of the pyridine ring [dihedral angle = 88.42 (3)°]. The two carbonyl units adopt a synperiplanar conformation with respect to the double bonds in the di­hydro­pyridine ring. In the crystal, mol­ecules are connected by N—H...O hydrogen bonds into R₄⁴(24) tetra­meric rings. A region of disordered electron density, located at the center of four adjacent mol­ecules, was treated with the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148–155]. It is probably the result of traces of the solvent of crystallization and was not taken into account during the structure refinement.
