In the title mol-ecule, C(21)H(32)F(2)N(3)O(2)P, the P=O and N-H groups are syn with respect to each other, and the P atom is bonded in a distorted tetra-hedral environment. The phosphoryl group adopts an anti orientation with respect to the carbonyl group. The angles at the tertiary N atoms (with bond-angle sums of 358.4 and 357.0°) confirm their sp(2) character. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
在标题分子C(21)H(32)F(2)N(3)O(2)P中，P=O和N-H基团彼此顺式排列，且P原子键合于扭曲的四面体环境中。磷酰基相对于羰基呈反式取向。叔氮原子处的角度（键角总和分别为358.4°和357.0°）证实了它们的sp(2)特征。在晶体中，由N-H⋯O氢键对连接的反演二聚体形成R(2) (2)(8)环。
