How is 2,6-Dibromo-3-nitropyridine (CAS: 55304-80-8) typically synthesized?

2,6-Dibromo-3-nitropyridine can be synthesized through a nitration reaction of 2,6-dibromopyridine with nitric acid in the presence of concentrated sulfuric acid as a catalyst. The reaction is carried out at high temperatures to ensure high yields. The key parameters include temperature control and the use of protective equipment to handle the corrosive and potentially toxic reactants.
