Abstract: The P atom in the title compound, C21H21FN3O2P, is in a tetrahedral coordination environment and the environment of each N atom is essentially planar (sums of angles = 359.7, 359.9 and 358.4°). The phosphoryl and carbonyl groups adopt anti orientations with respect to each other. In the crystal, adjacent molecules are linked via N-H
O=P and two N-H
O=C hydrogen bonds into an extended chain parallel to the a axis.
