4-[2-(Benzyl­amino)­phen­yl]-2,6-dimethyl­quinoline N-oxide

The title compound, C₂₄H₂₂N₂O, was obtained in a two-step procedure from the corresponding 4-(2-iodo­phen­yl)quinoline. The quinoline system is approximately planar [maximum deviation from the least-squares plane = 0.021 (2) Å]. The planes of the quinoline system and the phenyl ring subtend a dihedral angle of 78.08 (8)°. In the crystal, pairs of mol­ecules are connected via a center of symmetry and linked by a pair of angular N—H...O hydrogen bond. These dimers form columns oriented along the c axis.
