Synthesis of Some Novel Imidazolinone Derivatives with Dibenzo (b,f) azepine Nucleus.

Arylidene-2-phenyl-5-(4H)-oxazolones 1a-j were prepared by Erylenmeyer condensation. The 4-Arylidene-2-phenyl-5-(4H)-oxazolones react with p-phenylene diamine in presence of dry pyridine to give corresponding 3-(4-amino-phenyl)-5- benzylidene-2-substituted phenyl-3,5-dihydro-imidazol-4-one 2a-j, this was further reacted with dibenzo (b,f) azepine-5-carbonyl chloride 3 in basic medium to give dibenzo (b,f) azepine-5-carboxylic acid(4-(4-subtituted -5-oxo-2-phenyl-4,5-dihydro-imidazol-1- yl)-phenyl) amide 4a-j. The constitutions of the selected products is been supported by elemental analysis, Infrared (I.R) Spectra and 1 H-NMR Spectra. The purity of compounds
