چکیده
The molecular structure of the title compound, C(21)H(26)N(2)O(2), shows two intra-molecular O-H⋯N hydrogen-bonding inter-actions. In the crystal structure, mol-ecular chains are formed along the c axis through weak C-H⋯O inter-actions. Neighbouring chains are weakly associated along the a axis via C-H⋯π inter-actions.
