In the title molecule, iperidino)-1-(4-chlorophenyl)-2,5-pyrrolidinedi
one (1), the N-(p-chlorophenyl) substituent is rotated by 68.8-degrees
relative to the succinimide plane. The piperidinyl ring has a chair c
onformation with all substituents in equatorial positions; the conform
ation around the piperidino-succinimide C-N bond is staggered.
