In the title compound, C(27)H(30)N(2)O(4), the pyrrolidine ring adopts a twisted conformation. The indoline ring system is almost perpendicular to the mean plane of the pyrrolidine ring, making a dihedral angle of 81.7 (8)°. In the crystal, mol­ecules are linked into centrosymmetric dimers with grap...

description In the title compound, C(27)H(30)N(2)O(4), the pyrrolidine ring adopts a twisted conformation. The indoline ring system is almost perpendicular to the mean plane of the pyrrolidine ring, making a dihedral angle of 81.7 (8)°. In the crystal, mol­ecules are linked into centrosymmetric dimers with graph-set motif R (2) (2)(16) via pairs of C—H⋯O hydrogen bonds. The terminal ethyl group of the ester group is disordered over two sets of sites, with a site-occupancy ratio of 0.587 (11):0.413 (11).
