Methyl 3'-(2,5-di-methyl-benz-yl)-1'-methyl-2-oxo-4'-phenyl-spiro-[indoline-3,2'-pyrrolidine]-3'-carboxyl-ate chloro-form monosolvate.
In the title solvate, C29H30N2O3·CHCl3, the dihedral angle between the indole ring system (r.m.s. deviation = 0.050 Å) and the 4-methyl-pyrrolidine ring is 88.88 (8)°. The latter ring adopts an envelope conformation with the N atom as the flap. Its mean plane makes dihedral angles of 86.94 (11) and 42.08 (9)° with the phenyl and di-methyl-benzene rings, respectively. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen bonds, which generate S(6) and S(9) ring motifs. The chloro-form solvent mol-ecule is linked to the organic mol-ecule by a C-H⋯O hydrogen bond involving the carbonyl O atom of the carboxyl-ate group. In the crystal, mol-ecules are linked via bifurcated N-H⋯(N,O) and C-H⋯O hydrogen bonds, forming chains propagating along [001].
