In the title compound, C19H20F2N2O, the six-membered piperazine group adopts a slightly distorted chair conformation. The dihedral angle between the mean planes of the two benzene rings is 73.4 (6)°. The mean plane of the ethanone group is twisted from the mean planes of the two benzene rings by 66.7 (8) and 86.2 (6)°. In the crystal, C—H⋯O and C—H⋯F inter­actions link the molecules, forming a three-dimensional structure.
