| titleOfInvention | The preparation method of (1-benzhydryl-3-azetidinol) cyanoacetate |
| abstract | The invention relates to a preparation method of (1-benzhydryl-3-azetidinol) cyanoacetate, and relates to the technical field of application of azelnidipine in pharmaceutical and chemical technology. In the present invention, 1-benzhydryl-3-azetidinol, cyanoacetic acid and activator are pumped into the reactor, and during the reaction process, the reaction feed liquid is pumped into the external circulation dewatering system filled with dewatering agent to circulate dewatering , That is, (1-benzhydryl-3-azetidinol) cyanoacetate. In this step of the reaction process, the water generated in the reaction process can be effectively removed through the external circulation water removal device, reducing the loss of 1-benzhydryl-3-azetidinol and cyanoacetic acid, and achieving low energy consumption, simplicity and speed The production of (1-benzhydryl-3-azetidinol) cyanoacetate yield is greater than 93%, and the utilization rate of the reaction substrate is obviously improved. |
