Some fluoro- and iodo-derivative of 5-[[4-[(4-diisobutylamino)butyl]-1- phenyl]acetyl]-10,11-dihydro-5H-dibenzo[b,e][1,4]diazepin-11-one and 11-[[4- [(dialkylamino)butyl]-1-phenyl]acetyl]-5,11-dihydro-6H-pyrido[2,3- b][1,4]benzodiazepin-6-ones 6 (Scheme 1) and their analogues were synthesized. The synthesis of dibenzodiazepinones 1 (Scheme 1) is based on the reaction between 1,4-phenylenediamine and substituted benzoic acids. The intermediate pyridobenzodiazepinones 3 (Scheme 1) were prepared by condensation of 2-chloro-3-aminopyridine with methyl anthranilate and its chlorine derivative. The condensation of 4-[(halo)alkyl]phenylacetyl chloride with dibenzodiazepinones and pyridobenzodiazepinones followed by the reaction of mono- or dialkyl- or dialkenylamine provides 6 (Scheme 1).
