3-Bromo-2-chloro-5-nitropyridin-4-amine is an aromatic heterocycle that has been used as a precursor to other nitro compounds. It is prepared by reacting 3,4-dichloropyridine with nitric acid and bromine in the presence of sodium hydroxide. This reaction produces the nitro compound 3-bromo-2,4,5-trimethylpyridine. The optimum temperature for this reaction is 160°C and it utilizes triflate as a catalyst. The benzo group on the compound can be substituted or unsubstituted. 3-Bromo-2,4,5,-trimethylpyridine has two functional groups: an amine group and a nitro group. Heterocycles that contain two or more nitrogen atoms are called heteroaromatic compounds. Nitrogen atoms in heterocycles can be found in rings of
