As a common heterocyclic compound, it belongs to naphthyridine compound, name is 7-Bromo-2-chloro-1,5-naphthyridine, and cas is 1309774-03-5, its synthesis route is as follows.
0478-3 A suspension 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), and potassium acetate (39 mg) in 1,4-dioxane (2 mL) was stirred at 80 C. for 2 hours in a nitrogen atmosphere. 1-(4-(4-Iodo-1H-pyrazol-1-yl)piperidin-1-yl)ethanone (75 mg), sodium carbonate (42 mg) and bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (14 mg) were added to the reaction mixture, followed by stirring at 80 C. for 3 hours. The reaction mixture was cooled to room temperature, the insolubles were filtered off, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (methanol-ethyl acetate), thereby obtaining 1-(4-(4-(6-chloro-1,5-naphthyridin-3-yl)-1H-pyrazol-1-yl)piperidin-1-yl)ethanone (35 mg). MS m/z (M+H): 356.
