Abstract

The title compound, C(20)H(18)ClN(3)O(3), is in an enamine-keto form, stabilized by two strong intra-molecular N-H⋯O hydrogen bonds. The pyrazole ring is oriented at dihedral angles of 4.13 (3) and 85.60 (3)° with respect to the aromatic rings. The dihedral angle between the aromatic rings is 81.79 (3)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into double chains, which are further linked by weak C-H⋯π inter-actions, forming a two-dimensional network.
