Bottom Line: The quinoxaline and indane rings are each essentially planar, with r.m.s. deviations of 0.027 (1) and 0.0417 (1) Å, respectively.The pyrrolidine ring forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively.A weak intra-molecular C-H⋯N inter-action is observed.

ABSTRACT
In the title compound, C30H27ClN4O, the central pyrrolidine ring adopts an envelope conformation with the methyl-ene C atom being the flap. The quinoxaline and indane rings are each essentially planar, with r.m.s. deviations of 0.027 (1) and 0.0417 (1) Å, respectively. The pyrrolidine ring forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively. A weak intra-molecular C-H⋯N inter-action is observed. In the crystal, C-H⋯π inter-actions lead to supra-molecular chains along [101] that assemble in the ac plane. Connections along the b axis are of the type Cl⋯Cl [3.6538 (16) Å].
