Diethyl 2,6-dimethyl-4-phenyl-1,4-dihydropyridine-3,5-dicarboxylate

Abstract

The title molecule, C19H23NO4, was synthesized by the reaction of benzaldehyde, ethyl acetoacetate and NH4HCO3. The dihydropyridine ring adopts a flattened boat conformation and the plane of the base of the boat forms a dihedral angle of 88.78 (9)° with the phenyl ring. The packing is stabilized by strong intermolecular N—H...O and weak intermolecular C—H...O hydrogen bonds.
