چکیده
In the title compound, C(28)H(23)N(3)O(4), the dihedral angle between the quinoline and indole ring systems is 29.30 (5)°. The pyrrolidine ring adopts a twist conformation. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. A weak intra-molecular C3-H3⋯O3 inter-action is also observed. In the crystal, mol-ecules are linked by two sets of N-H⋯O hydrogen bonds, forming centrosymmetric dimers containing two R(2) (2)(8) ring motifs. The dimers are linked via C-H⋯π inter-actions.
