HCID 41405531-(2-Chlorophenyl)pyrrolidin-2-oneYield 25.4%

Procedure

Following example 19, 12.57 g (0.1 M) of 2-chloroaniline and 9.5 g (0.11 M) of γ-butyrolactone were heated for 48 hours. The excess starging materials were removed at 50°-80°/0.3 mm. Distillation of the residue gave 4.9 g (25%) of product (45% based on recovered 2-chloroaniline); b.p. 150°-155°/0.3-0.4 mm.
