An exceedingly facile protocol to the hetero-annulation of face ‘d’ of benzazepinone with quinoline nucleus has been developed. The synthesis proceeded with the formation of the key intermediate 7-fluoro-benzazepin-2,5-dione (2) which resulted from the acylation of p-fluoroaniline with succinyl chloride followed by treatment with PPA. Compound 2 underwent a very smooth Pfitzinger reaction with isatin to furnish the acid 3, the hydrazide of which reacted rapidly with reagents indicated in (Scheme 1-2) to afford the corresponding oxadiazole, triazole and pyrazole incorporated analogues 5-9 respectively in acceptable yields.
