2-(2H-Benzotriazol-2-yl)-6-[(dicyclo­hexyl­amino)­meth­yl]-4-(2,4,4-trimethyl­pentan-2-yl)phenol

In the title mol­ecule, C₃₃H₄₈N₄O, the dihedral angle between the mean planes of the benzotriazole ring system [maximun deviation = 0.038 (2) Å] and the phenol ring is 16.6 (2)°. There is an intra­molecular O—H...N hydrogen bond between the phenol and benzotriazole groups.
