Abstract: In the title compound, C17H17BrN2O, the N-containing ring adopts an envelope conformation with the C atom carrying the phenyl ring displaced by -0.531 (9) Å from the plane defined by the remaining five atoms (r.m.s. deviation = 0.0099 Å). The benzene ring is almost orthogonal to the ring to which it is attached, the CCN-C-CPh-CPh torsion angle being -101.3 (7)°. The cyclohexene ring is disordered over two conformations in a statistical ratio. The most prominent interactions in the crystal are pairs of N-H...O hydrogen bonds between inversion-related molecules. The resulting dimers are linked into a three-dimensional architecture by C-H...N, C-H...Br and C-H...[pi] interactions.
