Sumario: | The asymmetric unit of the title compound, C(23)H(22)N(2)O(2), contains two independent molecules, A and B. The cyclohexane ring of molecule B is disordered, with occupancies for the major and minor conformers of 0.570 (9) and 0.430 (9), respectively. The cyclohexane ring adopts a boat conformation in molecule A and in the major conformer of molecule B, and a chair conformation in the minor conformer of molecule B. In both independent molecules, one of the dihydropyran rings adopts a boat conformation while the other is in a half-chair conformation. The dihedral angle between the pyrazole and phenyl rings is 16.0 (1)° in molecule A and 12.9 (1)° in molecule B. The crystal packing is stabilized by C—H⋯O and C—H⋯N intermolecular hydrogen bonds. |
