were obtained from 1 and primary alkylamines, whereas the 1,4-diazepine derivative 10 was obtained from 1 and ethylenediamine. Treatment of the bis-base 1,4-di[β -(N-morpholino)propionyl]benzene bis(hydrochloride) (11) with primary arylamines gave the corresponding bis-(sec-arylamines) 12a - b, whereas its reaction with ophenylenediamine afforded the bis[1,5-benzodiazepine] ringsystem 14. The synthesis
