Use | dimethylpyridinamine is a heterocyclic organic compound and can be used as a pharmaceutical intermediate. |
preparation | add 2-aldopyridine (10mmol) in a ML three-necked flask, 20ml of a methanol solution of 2-aminomethylpyridine (10mmol) was added dropwise to 2-aldypyridine, and the mixture was stirred at room temperature for 10h after completion of the dropwise addition. NaBH4(20mmol) was slowly added to the reaction system, and the reaction solution changed from brown to light yellow. After stirring overnight at room temperature, the solvent was evaporated under reduced pressure, and then 20ml of distilled water was added, the pH was adjusted to Neutral with 32% dilute hydrochloric acid under stirring, and the mixture was extracted with dichloromethane (3 × 30ml). The lower yellow solution was collected, dried over anhydrous MgSO4, and distilled under reduced pressure to obtain a yellow liquid in 95% yield. |
