1260670-05-0, 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. 3-Bromo-8-chloro-1,7-naphthyridine, cas is 1260670-05-0,the naphthyridine compound, it is a common compound, a new synthetic route is introduced below.
Step 1 To a 100 mL sealed tube was added 3~bromo-8-chloro-l,7-naphthyridine K-l (1.00 g, 4.10 mmol), 1,4-dioxane (15 mL) and NH3_H20 (40 mL) at room temperature. The mixture was sealed and stirred at 100 C for 15 h, then cooled and partitioned between water (150 mL) and EtOAc (100 mL). The aqueous layer was extracted with EtOAc (50 mL x 2) and the combined extracts were dried over sodium sulfate, filtered and concentrated in vacuo to afford compound K-2. MS for K-2: m/e = 224 and 226 (M+l).
The chemical industry reduces the impact on the environment during synthesis,1260670-05-0,3-Bromo-8-chloro-1,7-naphthyridine,I believe this compound will play a more active role in future production and life.
