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.
0421-1 A mixture of 7-bromo-2-chloro-1,5-naphthyridine (48 mg), bis(pinacolato)diboron (58 mg), a 1,1′-bis(diphenylphosphino)ferrocenepalladium(II) dichloride-dichloromethane complex (16 mg), potassium acetate (42 mg), and 1,4-dioxane (1.9 mL) was stirred at 100 C. for 2 hours. N-(4-bromopyridin-2-yl)acetamide (42 mg), sodium carbonate (45 mg), a bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (14 mg), 1,4-dioxane (0.3 mL), and water (0.19 mL)) were added to the reaction mixture, followed by stirring at 100 C. for 2 hours. The reaction mixture was cooled to room temperature, and purified by silica gel column chromatography (hexane-ethyl acetate-methanol), thereby obtaining N-(4-(6-chloro-1,5-naphthyridin-3-yl)pyridin-2-yl)acetamide (12.6 mg) as a pale brown solid. MS m/z (M+H): 299.
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.
