Title: Optical resolution of 1-ethyl-2-aminomethyl-pyrrolidine
IPC: C07D207/09
Filed: 1974-02-28
Abstract: The dextrorotatory and laevorotatory isomers of 1-ethyl-2-aminomethyl-pyrrolidine (I): None stated. By treatment of (I) with d- and 1-tartaric acid. A solution of (I) is treated with d-tartaric acid. d-(I) d-tartrate crystallizes out and is isolated. The mother liquors, containing 1-(I) and d-(I) in the form of their d-tartrates, are basified and 1-(I) and d-(I) are extracted therefrom. The mixture obtained is treated with 1-tartaric acid to yield crystalline 1-(I) 1-tartrate in good yield. The optically active bases are obtained from the respective tartrates by basifying an aqueous solution thereof and subsequently extracting or distilling the base released. It is possible to prepare the 1-tartrates of d- and 1-(I) first of all, but this makes the operation more costly because of the expensiveness of 1-tartaric acid.
