| titleOfInvention | Preparation process of imidazopyrazine compound |
| abstract | The invention discloses a preparation process of imidazopyrazine compounds, which is characterized in that specific alkali and a condensing agent are selected, parameters in a reaction system are adjusted, a post-crystallization and pulping treatment method is used for replacing a column chromatography method in the prior art, and an HBR-101 pure product can be obtained by one-step purification, so that the product yield is obviously improved, the problems of high difficulty in large-scale production operation, high cost and the like are solved, the environmental influence is reduced, and the preparation process is particularly suitable for industrial production and commercial application. |
