254-79-5, 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. 1,5-Naphthyridine, cas is 254-79-5,the naphthyridine compound, it is a common compound, a new synthetic route is introduced below.
3-Bromo-1,5-naphthyridine (5) To a stirring solutionof compound 4 (2.7 g, 20.76 mmol) and NaOAc(3.41 g,41.52 mmol) in 10 mL glacial AcOH at 85C was added a solution of Br2 (1 M) in AcOH (35 mL) for 5 h,then cooled to room temperature and concentrated in vacuum to remove AcOH.Purification by chromatography (PE/EA = 2:1) provided compound 5 (2.36 g, 55%) as a whitesolid. MP: 107~108C (Ref.2 108~109C).1H NMR (400 MHz,CDCl3): delta 8.96 (d, J = 2.1 Hz, 2H), 8.56 (s, 1H), 8.36 (d, J = 8.5 Hz, 1H), 7.69-7.56 (m, 1H).
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 1,5-Naphthyridine, 254-79-5
