Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 57489-77-7, name is 5,7-Dichloropyrazolo[1,5-a]pyrimidine. A new synthetic method of this compound is introduced below., Product Details of 57489-77-7
General procedure: To a well stirred 8-aminoquinoline (1 mmol) indry DMF (5 mL), sodium hydride (1.2 mmol, 60% in mineral oil) was added at 0 C.After 10 min stirring, the corresponding heterocyclic chloro compound (1.2mmol) was added and stirred for 10 min at rt then heated at 60 C for 5-12 h.Upon completion, the reaction mixture was poured into crushed ice and theresulting solid was filtered, washed with water and dried under vacuum. Thesolid was triturated with methanol and dried under vacuum to afford targetcompound as a solid.
