W-MethyW-nitrophthalimide ( 4-NPI) was reduced by metal such as iron powder in dilute acidic solution and then hydrolyzed in solution of sodium hydroxide to provide di-sodium 4-aminophthalate. The Sandmeyer reaction of di-sodium 4-aminophthalate in hydrobromic acid gave 4-bromophthalic anhydride (4-BPA) .

Key words: methyl-4-nitrophthalimide;IRON;PHTHALIC ANHYDRIDE P;BROMINE COMPOUNDS, REDUCTION
