The naphthyridine compound, cas is 1309774-03-5 name is 7-Bromo-2-chloro-1,5-naphthyridine, mainly used in chemical industry, its synthesis route is as follows.
0393-3 A mixture of 7-bromo-2-chloro-1,5-naphthyridine (80 mg), 3-(((tert-butyldimethylsilyl)oxy)methyl)-1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (231 mg), sodium carbonate (87 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (23 mg), water (0.3 mL), and 1,4-dioxane (3 mL) was stirred at 80 C. for 2 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 7-(3-(((tert-butyldimethylsilyl)oxy)methyl)-1-methyl-1H-pyrazol-4-yl)-2-chloro-1,5-naphthyridine (76 mg). MS m/z (M+H): 389.
