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

P. Zhang and W. Zhu

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.
