Purification technology of vildagliptin intermediate 3-amino-1-adamantanol |
| abstract |
The invention discloses a purification technology of vildagliptin intermediate 3-amino-1-adamantanol. According to the purification technology, a water system (water, water-alcohol or water-toluene) is used, and methods of regulating acid for dissolving and regulating alkali for separating out are adopted, so that a 3-amino-1-adamantanol crude product can be purified. The purification technology is remarkable in purification effect and capable of controlling crystal forms precisely to facilitate raw control for preparing vildagliptin in next step. |
