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

Abstract

In the title compound, C19H21Cl2NO4, the dihydropyridine ring adopts a flattened boat conformation. The dichlorophenyl ring is oriented almost perpendicular to the planar part of the dihydropyridine ring [dihedral angle = 89.1 (1)°]. An intramolecular C—H...O hydrogen bond is observed. In the crystal structure, molecules are linked into chains along the b axis by N—H...O hydrogen bonds
