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.
0022-1 Several drops of a 4 mol/L hydrogen chloride-1,4-dioxane solution (3 mL) and water were added to 7-bromo-2-chloro-1,5-naphthyridine (250 mg), followed by stirring at 100 C. overnight. The reaction mixture was cooled to room temperature, and water was added thereto. The solid matter was collected by filtration, and washed with a mixture solution of water and hexane-ethyl acetate (1:1), thereby obtaining 7-bromo-1,5-naphthyridin-2-ol (190 mg) as a grey solid. 1H-NMR (DMSO-d6) delta: 11.96 (1H, brs), 8.56 (1H, d, J=2.3 Hz), 7.93 (1H, d, J=9.9 Hz), 7.85 (1H, d, J=2.30 Hz), 6.79 (1H, d, J=9.9 Hz).
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
