Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 886371-28-4, name is 3-Bromo-6-chloroimidazo[1,2-a]pyridine. A new synthetic method of this compound is introduced below., Formula: C7H4BrClN2
To a solution of 3-bromo-6-chloro-imidazo[1,2-a]pyridine (1 eq, 18.1 mmol, 4.2 g), 2- chloropyridin-4-yl boronic acid (1.05 eq, 19 mmol, 3 g), Na2COs (2 eq, 36.2 mmol, 3.84 g) in dioxane (30 ml) and water (10 ml), under an inert atmosphere of argon is added bis(triphenylphosphine)palladium II chloride (1.23 g). The reaction mixture is heated at 100 C for 16 hours. The mixture is diluted with H2O (50 ml) and extracted with EtOAc. The combined organic portions are washed with brine, dried (MgStheta4) and concentrated in vacuo. The residue is purified by flash chromatography on silica eluting with 0-50% EtOAc in iso-hexane to afford the title compound; [M+H]+ =264 (266).
