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.
Example 0757 0757-1 A mixture of 7-bromo-2-chloro-1,5-naphthyridine (600 mg), 1,3-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (442 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (174 mg), sodium carbonate (522 mg), 1,4-dioxane (24 mL), and water (2.4 mL) was stirred at 100 C. for 3 hours in a nitrogen atmosphere. The reaction mixture was cooled to room temperature, and the solvent was distilled off under reduced pressure. The reaction residue was purified by silica gel column chromatography (chloroform-methanol, NH silica), thereby obtaining 2-chloro-7-(1,3-dimethyl-1H-pyrazol-4-yl)-1,5-naphthyridine (412 mg) as a white solid. MS m/z (M+H): 259.
The chemical industry reduces the impact on the environment during synthesis,1309774-03-5,7-Bromo-2-chloro-1,5-naphthyridine,I believe this compound will play a more active role in future production and life.
