چکیده
In the title compound, C22H25ClN2O, the pyrazole ring exhibits an envelope conformation with the methine C atom as the flap. The benzene rings are twisted by 3.3 (5) and 84.6 (5)° from the pyrazole mean plane, and are inclined to each other by 81.4 (4)°. In the crystal, pairs of weak C-H⋯O hydrogen bonds form centrosymmetric dimers with an R 2 (2)(16) graph-set motif. C-H⋯π inter-actions link the dimers into columns propagating in [100].
