(E)-4-tert-Butyl-2-(2,6-diisopropyl-phenyl-imino-meth-yl)-6-(morpholinometh-yl)phenol.

In the mol-ecule of the title compound, C(28)H(40)N(2)O(2), the tert-butyl group is disordered over two positions; site-occupation factors were kept fixed at 0.5. The morpholine ring has a chair conformation. Intra-molecular O-H⋯N hydrogen bonding results in the formation of a planar six-membered ring, which is oriented at a dihedral angle of 0.70 (3)° with respect to the adjacent aromatic ring. The dihedral angle between the benzene rings is 67.66 (3)°.
