7-Bromo-2-chloro-1,5-naphthyridine, cas is 1309774-03-5, it is a common heterocyclic compound, the naphthyridine compound, its synthesis route is as follows.
0399-2 A mixture of 7-bromo-2-chloro-1,5-naphthyridine (48 mg), bis(pinacolato)diboron (60 mg), (1,1′-bis(diphenylphosphino)ferrocene)palladium(II) dichloride (16 mg), potassium acetate (39 mg), and 1,4-dioxane (2 mL) was stirred at 80 C. for 2 hours in a nitrogen atmosphere. 4-(4-Iodo-1H-pyrazol-1-yl)pyridine (75 mg), sodium carbonate (42 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (14 mg), and water (0.2 mL) were added thereto, followed by stirring at 80 C. for 8 hours. The reaction mixture was cooled to room temperature, the insolubles were filtered off using celite, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (methanol-ethyl acetate-hexane), thereby obtaining 2-chloro-7-(1-(pyridin-4-yl)-1H-pyrazol-4-yl)-1,5-naphthyridine (29 mg). MS m/z (M+H): 308.
With the rapid development of chemical substances, we look forward to future research findings about 1309774-03-5
