TIMTEC-BB SBB003823 - Reference Information
| Application | 5-amino-2-bromopyridine is also called 6-bromopyridine -3-amine, which can be reduced by 2-bromo-5-nitropyridine The nitro group is obtained, and the reducing agent can be selected from iron powder; 6-bromopyridine -3-amine can also be obtained after bromination of 3-aminopyridine. |
| preparation | acetonitrile (250ml) and 3-aminopyridine (20g,0.212mol) are added to the reaction bottle in sequence, and stirred and dissolved. Under the condition of ice bath, N-bromosuccinimide (38g,0.212mol) was slowly added to it, stirred for 15min, the ice bath was removed, and the reaction was carried out overnight at room temperature. The solvent is unscrewed under reduced pressure, the concentrate is dissolved with ethyl acetate and water, the insoluble matter is filtered and extracted, the organic phase is washed with water and salt water, and anhydrous sodium sulfate is added to dry. Filtration, solvent extraction, column to obtain compound 11, orange solid, 7.4g, 20.2% yield. |
