(5''E)-1''-Benzyl-1'-methyl-5''-[4-(methyl-sulfan-yl)benzyl-idene]-4'-[4-(methyl-sulfan-yl)phen-yl]dispiro-[indoline-3,2'-pyrrolidine-3',3''-piperidine]-2,4''-dione dichloro-methane solvate.

In the title compound, C(38)H(36)N(3)O(2)S(2)·CH(2)Cl(2), the 2-oxindole ring is almost planar (r.m.s. deviation = 0.032 Å), the pyrrolidine ring adopts a twist conformation and the piperidone ring exists as a chair. Three short C-H⋯O intra-molecular contacts occur. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N inter-actions. The dichloro-methane solvent mol-ecule is disordered over two orientations in a 0.765 (11):0.235 (11) ratio.
