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. 868-54-2, name is 2-Aminoprop-1-ene-1,1,3-tricarbonitrile, A new synthetic method of this compound is introduced below., name: 2-Aminoprop-1-ene-1,1,3-tricarbonitrile
General procedure: Et3N (0.3 mmol) was added to a stirred solution of salicylaldehyde (3 mmol), 2-aminoprop-1-ene-1,1,3-tricarbonitrile (3 mmol) and 3-trifluoromethyl-2-pyrazolin-5-one in 5 ml of n-PrOH at ambient temperature. Then mixture was refluxed for 4 h. After the reaction was finished and cooled the solid was filtered and dried to isolate pure substituted 2,4-diamino-5-(5-hydroxy-3-(trifluoromethyl)-1H-pyrazol-4-yl)-5H-chromeno[2,3-b]pyridine-3-carbonitrile. In some cases cristallisation from EtOH-DMSO is needed.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
