Synthesis of 4,4'-dibromobipyridine CAS: 18511-71-2 :

in acetic acid, 4,4' -dinitro-2,2' -bipyridine nitrogen oxides were added and heated up to reflux. Acetylbromoacetic acid solution was added. At the end of the reaction, could added the reducing agent,then  synthesis of  the 4,4'-dibromobipyridine CAS: 18511-71-2 .
