METHOD FOR PREPARING N-SUBSTITUTED PYRROLIDONE |
| abstract |
1-Chloromethyl-2-pyrrolidone is reacted with CuCN in suitable solvent to give (I; X = CN) which is distilled in vacuum, then partly hydrolysed by using an ion-exchange resin such as 'Lewatite' (RTM), to give (I; X = CONH2) in very high purity. 2-Oxo-1-pyrrolidinyl acetamide is a known cpd. with selective activity on the large cerebral cortex giving activating, protecting and recuperative action on nerve cells. |
