Diethyl 4-[5-(4-chloro-phen-yl)-1H-pyrazol-4-yl]-2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate

Abstract

In the title compound, C(22)H(24)ClN(3)O(4), intra-molecular C-H⋯O and C-H⋯N hydrogen bonds form S(9) and S(7) ring motifs, respectively. The 1,4-dihydro-pyridine ring adopts a flattened boat conformation. The benzene ring makes a dihedral angle of 33.36 (6)° with the pyrazole ring. In the crystal, pairs of N-H⋯N hydrogen bonds link the mol-ecules into inversion dimers. The dimers are stacked in column along the a axis through N-H⋯O and C-H⋯N hydrogen bonds. The crystal packing also features C-H⋯π inter-actions involving the pyrazole ring.
