| titleOfInvention | Synthetic method of biphenyl diester intermediate |
| abstract | The invention belongs to the field of chemical pharmacy, and particularly discloses a method for synthesizing a biphenyl diester intermediate. The synthesis method of the bifendate intermediate adopts phosgene to protect the hydroxyl of the catechol, has complete protection, mild reaction conditions, simple process and convenient operation. Through the exploration and optimization of conditions, the product yield and purity are high, the problem of wastewater in a borax protection method is solved, the environment is not damaged, the treatment of industrial wastewater in the later period is reduced, the production cost of the whole process is reduced to the maximum extent, and the method has extremely high application. |
