In the title compound, C21H19F2NO2, the cyclohexa-1,3-diene ring is in a distorted envelope conformation. The dihedral angles between the mean planes of the diene moiety and the two fluorophenyl rings are 42.8 (2) and 75.0 (5)°. The two fluorophenyl rings are inclined to one another by 87.0 (3)°. In the crystal, intramolecular N—H⋯O hydrogen bonds and weak N—H⋯O and N—H⋯F intermolecular interactions are observed forming an infinite two-dimensional network along [011].
