In the mol-ecule of the title compound, C(19)H(23)N(3)O(3), the six-membered rings are oriented at a dihedral angle of 73.06 (3)°. The cyclo-pentyl ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules. In the tolyl ring, the H atoms and all but one of the C atoms are disordered over two positions and were refined with occupancies of 0.51 (3) and 0.49 (3).
