1309774-03-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7-Bromo-2-chloro-1,5-naphthyridine, cas is 1309774-03-5,the naphthyridine compound, it is a common compound, a new synthetic route is introduced below.
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.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7-Bromo-2-chloro-1,5-naphthyridine, 1309774-03-5
