The asymmetric unit of the title compound, C22H23F2NO, contains two independent mol-ecules, A and B. The bicyclic system adopts a twin-chair conformation in both mol-ecules. The dihedral angles between the fluoro-phenyl rings are 55.27 (8) and 56.37 (7)° in mol-ecules A and B, respectively. The NH groups are not involved in hydrogen bonding due to the steric hindrance of fluoro-phenyl groups. The crystal structure features weak C-H⋯O inter-actions.
标题化合物C22H23F2NO的不对称单元包含两个独立分子，A和B。双环体系在两个分子中均采用双椅构象。分子A和B中氟苯环之间的二面角分别为55.27 (8)°和56.37 (7)°。由于氟苯基的空间位阻，NH基团不参与氢键形成。晶体结构具有弱的C-H⋯O相互作用。
