a series of [ 4- ( 6h/bromo-4-oxo-2-phenyl-3 ( 4h ) -quinazolinyl ) phenoxy ] acetic acid ( 1,2-dihydro-1-h/methyl-2-oxo-3h-indol-3-ylidene ) hydrazides ( vii1-16 ) were synthesised by condensing 1-h/methyl-5-substituted indoline-2,3-diones with [ 4- ( 6h/bromo-4-oxo-2-phenyl-3 ( 4h ) -quinazolinyl ) phenoxy ] acetic acid hydrazides ( iv1-2 ) which in turn were obtained by reacting ethyl [ 4- ( 6h/bromo-4-oxo-2-phenyl-3 ( 4h ) -quinazolinyl ) phenoxy ] acetates ( iii1-2 ) with hydrazine hydrate .
