7689-62-5, 2-Chloro-1,5-naphthyridine is a naphthyridine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
7689-62-5, A solution of the compound 0001-2 (2.88 g) and sodium acetate (2.89 g) in acetic acid (15 mL) was stirred at 85C for 5 minutes. A solution of bromine (0.99 mL) in acetic acid (2.5 mL) was dropwise added thereto. Further acetic acid (2 mL) was added dropwise thereto, and the mixture was stirred at 85C for 3 hours. To a 6 M aqueous sodium hydroxide solution (60 mL) under stirring with ice-cooling, the reaction solution which had been cooled to room temperature was added dropwise. The precipitated solid was separated by filtration, and the solid was then suspended in methanol (5 mL), and thereafter subjected to sonication. Thereafter, the suspension was filtered, and then the resulting solid was washed with methanol (3 mL). The obtained solid was suspended in a 75 v/v% aqueous methanol solution (8 mL), subjected to sonication, and then the suspension was filtered, and the residue was then washed with a 75 v/v% aqueous methanol solution twice to obtain a compound 0001-3 (3.33 g) as a pale yellow solid. 1H-NMR (DMSO-d6) delta: 9.13 (1H, d), 8.77 (1H, dd), 8.53 (1H, dd), 7.91 (1H, d). MS m/z (M+H): 245.
7689-62-5 2-Chloro-1,5-naphthyridine 15153031, anaphthyridine compound, is more and more widely used in various.
