Diethyl 2,6-dimethyl-4-(5-phenyl-1H-pyrazol-4-yl)-1,4-dihydropyridine-3,5-dicarboxylate

Abstract

In the title compound, C22H25N3O4, the dihydropyridine ring adopts a flattened boat conformation. The pyrazole ring makes a dihedral angle of 29.04 (5)° with the benzene ring. The molecular structure is stabilized by an intramolecular C—H...O hydrogen bond which generates an S(9) ring motif. In the crystal, molecules are linked via N—H...O and C—H...N hydrogen bonds into a two-dimensional network parallel to the ab plane. The crystal structure is further consolidated by weak C—H...π interactions.
