چکیده
In the title compound, C(19)H(24)N(2)O(3), the benzene ring forms a dihedral angle of 65.34 (7)° with the pyrazole ring. The cyclo-hexane ring adopts a chair conformation. In the crystal, mol-ecules are linked into a inversion dimers by pairs of C-H⋯O hydrogen bonds, generating R(2) (2)(22) ring motifs.
