ABSTRACT:
This invention relates to a series of 1-iminomethylindolines which are analeptic agents capable of counteracting central nervous system depressant effects of pentobarbital and chloral hydrate. They also exhibit analgesic effects. This invention also relates to a process for the preparation of 1-iminomethylindolines which comprises reaction of an indoline with carboxamides selected from the group consisting of amides, lactams, symmetrical or unsymmetrical ureas and hydrazides. Typical examples of 1-iminomethylindoline derivatives are 5-acetyl-1-[2-(1-pyrrolinyl)]indoline and 1-[2-(5,5-dimethyl-1-pyrrolinyl)]indoline.
