Synthesis of 4-aryl-2H-phthalazin-1-ones 5 and their successive conversion, via the Mannich reaction into 2-[(dialkylamino)-methyl]-4-aryl-2H-phthalazin-1-ones 6, 7, 8, 9 as a way of regiospecific transformation of the 4-methoxybenzanilide 1, is described. In addition, the compounds 5b and 7 appeared to be effective complexing ligands for such metal as Cu(II), Ni(II), Fe(II), and Fe(III).
