2,4-Di-tert-butyl-6-({[2-(di-methyl-amino)-eth-yl](2-hy-droxy-benz-yl)amino}-meth-yl)phenol.

The title compound, C26H40N2O2, has both its N atoms in trigonal-pyramidal geometries. The mol­ecular structure is stabilized by O—H⋯N and C—H⋯O hydrogen bonds. In the crystal, C—H⋯π inter­actions lead to the formation of a supramolecular helical chain along the b-axis direction.
