Versuchsvorschrift

To 90 ml of water containing 10 g of sodium hydroxide was added 5.0 g of 1-benzyl-3-cyanomethyl-2-(2,6-dichlorophenyl)pyrrolidin-5-one. The reaction was refluxed 5 hours, cooled, and filtered. Extraction of the aqueous phase with ether followed by addition of ice and acidification with concentrated hydrochloric acid gave a solid which was then triturated with ether to yield beige crystals. Vacuum drying (0.1 Torr) under refluxing toluene for 15 hours followed by recrystallization from ethanol provided upon drying 1.50 g of colorless crystals, m.p. 186°-188°.
