The method of preparation of the 3-aryl-6,7,8,9-tetrahydro-5H- imidazo[1,2-a]azepines 2a-d from O-methylcaprolactim and phenacylamine hydrochlorides has been developed. The bases 2 reacted with phenacylbromides to yield the quaternary salts 4a-c. The cyclisation of 4a-c in basic conditions resulted in a new heterocyclic system - the derivatives of 2a,4a- Diazaclopenta[c,d]azulene - 5a-i.
