(2-OXO-PYRROLIDENE-1) ACETIC HYDRAZIDES AND PROCESS FOR PREPARATION

摘要

(2-Oxo-pyrrolldine-1) acetic hydrazides of the formula I (I) wherein R1 denotes a hydrogen atom or a compound of the formula II (II) are prepared by reacting (2-oxo-pyrrolidine-1) acetic ester of the formula III (III) wherein R2 denotes a lower alkyl group having 1-4 C-atoms, with hydrazine or with a hydrazine derivative of said formula I, wherein R1 denotes a hydrogen atom. The novel compounds are useful as psychopharmacons, i.e. as nootropic substances for influencing learning capacity, and also as intermediates for the production of (2-oxo-pyrrolidine-1-acetamide.
