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