The isomeric 5-bromo- and 6-bromo-3-benzalphthalides were prepared by condensation of 4-bromophthalic anhydride with phenylacetic acids. The reaction of such isomeric bromobenzalphthalides with primary aromatic amines give the corresponding bromobenzalphthalimidines. Bromophthalazinone derivatives were obtained in good yields by the reatcion of bromobenzalphthalides with hydrazine hydrate.
