Methyl 3'-benzyl-4'-(2,4-di-chloro-phen-yl)-1'-methyl-2-oxo-1-propyl-spiro-[indoline-3,2'-pyrrolidine]-3'-carboxy-l-ate.
In the title compound, C30H30Cl2N2O3, the indole ring system is roughly planar, with a maximum deviation of 0.1039 (18) Å for the carbonyl C atom, and makes a dihedral angle of 86.61 (9)° with the mean plane of the pyrrolidine ring. This spiro pyrrolidine ring adopts an envelope conformation with the N atom at the flap position. The pyrrole ring of the indole ring system adopts a twisted conformation on the C-C(=O) bond. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif, and a π-π inter-action [centroid-centroid distance = 3.6577 (12) Å] involving the 2,4-di-chloro-phenyl ring and the benzyl ring. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming C(9) chains running parallel to [10-1].
