چکیده
In the title compound, C21H19BrFNO2, two independent mol-ecules crystallize in the asymmetric unit. The cyclo-hexa-1,3-diene ring is in a slightly distorted screw-boat conformation. The dihedral angles between the mean planes of the 4-bromo-phenyl and 4-fluoro-phenyl rings are 81.0 (3) and 76.4 (2)° in the two independent mol-ecules. In the crystal, N-H⋯O hydrogen bonds link the molecules into [100] chains.
