Here is a downstream synthesis route of the compound 13534-98-0.
3-Bromo-5-iodopyridin-4-amine A solution of potassium iodide (2.88 g, 17.34 mmol) and iodine (2.75 g, 10.84 mmol) in water (21 mL) was added dropwise to a solution of 4-amino-3-bromopyridine (2.5 g, 14.45 mmol) and sodium carbonate (0.919 g, 8.67 mmol) in water (10 mL) and the mixture was stirred at reflux for 20 h. The mixture was diluted with water and EtOAc and the layers were separated. The organic layer was extracted with EtOAc three times. The combined organic layers were washed with sat. Na2S2O3 three times, dried over MgSO4, filtered off and the filtrate concentrated in vacuum. The resulting brown oil was purified by chromatography on silica gel (biotage, CyHex/EtOAc, 50:50 to 0:100) to give product (951 mg, 22%) and starting material (1.66 g) as light yellow solids.
According to the analysis of related databases, 13534-98-0, the application of this compound in the production field has become more and more popular.
