These two rings are twisted to each other with N-C-C-N torsion angles around the connecting C-C bond of 48.9 (6) and -127.0 (5)°. The benzene ring is nearly perpendicular to the pyrrolidine ring, with torsion angles around the connecting C-C bond of 86.3 (6) and -97.7 (6)°. The crystal structure is stabilized by C-H⋯O and C-H⋯π hydrogen bonds, which build up a three-dimensional network.Acta crystallographica.
