cycloalkylene moiety as well as other modifications in the lipophilic part. The in vitro values for inhibition of [(3)H]-GABA uptake in rat synaptosomes was determined for each compound, and it was found that several of the novel compounds inhibit GABA uptake as potently as their known symmetrical reference analogues. Several of the novel compounds were also evaluated for their ability to inhibit clonic seizures

The present invention relates to therapeutically active azaheterocyclic compounds, a method of preparing the same and to pharmaceutical compositions comprising the compounds. The novel compounds are useful in treating a central nervous system ailment related to the GABA uptake.
3-phenyl-2-piperazinyl-5H-1-benzazepines and related compounds were synthesized and evaluated for potential neuroleptic activity. The preparation of these compounds was carried out by 2,3-dichlorination of 3-phenyl-2,3,4,5-tetrahydro-1H-1-benzazepin-2-ones with phosphoruspentachloride followed by amination and concurrent dehydrochlorination. Compounds having the 4-chloro or 4-fluoro substituent in the 3-phenyl
