In the title compound, C19H22N2O4, the dihedral angle between the aromatic rings is 67.33 (2)°. In the crystal, molecules are linked through N—HO and O—HO hydrogen bonds, generating a two-dimensional network lying parallel to (100). As a result of the twist of the molecular skeleton and the hindrance of the tert-butyl groups, no π–π interactions exist between the aromatic rings.
