5-Bromo-2-nitropyridine Chemical Properties,Usage,Production

Chemical Properties

Colorless solid

Uses

5-Bromo-2-nitropyridine is employed as a reagent in the synthesis of novel benzinidazoles, potent inhibitors of TIE-2 and VEGFR-2 Tyrosine (T899975) kinase receptors.

Preparation

5-Bromo-2-nitropyridine was prepared from the corresponding amine via hydrogen peroxide oxidation in large scale production. N-Bromosuccinimide (NBS) bromination of 2-aminopyridine in acetonitrile at 0-5 °C delivered 5-bromo-2- aminopyridine with good regioselectivity (>20:1). The brominated amino-pyridine was then reacted with the oxidant mixture, yielding 5-Bromo-2-nitropyridine after dilution with water and isopropanol[1].
