| titleOfInvention | Synthetic method of rebamipide intermediate |
| abstract | The invention discloses a key intermediate 2-amino-3- [2 (1) for synthesizing rebamipide H ) -quinolone-4]A novel process for the production of propionic acid. The method comprises the step of reacting aspartic acid with 2-hydroxyquinoline to prepare the rebamipide key intermediate 2-amino-3- [2 (1) H ) -quinolone-4]Propionic acid and p-chlorobenzoyl chloride are condensed to prepare rebamipide. The intermediate synthesis method has the advantages of cheap and easily-obtained raw materials, short reaction steps and good optical purity. 。 |
