A one step synthesis of functionlized N-acylanthranilamidevia Pd-catalyzed carboxamidation of o-halo substituted N-phenylamide consisting of isocyanideinsertion followed by oxidation of the imine intermediate has been achived successfully. Furthermore, at elevated temprature (160oC) the Pd-catalyzed tandem reaction afforded functionlized quinazolin-4-one in a single step without the isolation of
