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

Abstract

In the title compound, C20H22N2O4, the dihedral angle between the roughly planar dihydro­pyridine ring (r.m.s. deviation = 0.092 Å) and the benzene ring is 87.09 (6)°. One of the eth­oxy side chains is disordered over two orientations in a 0.669 (14):0.331 (14) ratio. In the crystal, mol­ecules are linked by N—H⋯N hydrogen bonds, generating chains
