With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1309774-03-5,7-Bromo-2-chloro-1,5-naphthyridine,as a common compound, the synthetic route is as follows.,1309774-03-5
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.
1309774-03-5 7-Bromo-2-chloro-1,5-naphthyridine 58310544, anaphthyridine compound, is more and more widely used in various fields.
