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. 5334-43-0, name is 5-Amino-1-phenyl-1H-pyrazole-4-carbonitrile, A new synthetic method of this compound is introduced below., Product Details of 5334-43-0<\/a><\/p>\n

General procedure: (General method). Amixture of the appropriate aminonitrile 1 (3.0 mmol) and1,3-dicarbonyl compound (3.0 mmol) in anhydrous toluene(12 ml) was refluxed for 1 h in a flask equipped with aDean-Stark trap. Tin(IV) chloride (3.0 g, 11.5 mmol) wasadded to the reaction mixture, and refluxing was continuedfor additional 5-6 h. A resinous precipitate was formed,andthe colorless toluene layer was decanted. The residualsolvent was removed on a rotary evaporator, the obtainedglassy solids were dissolved in boiling dioxane, cooled, thenpoured into a solution of Na23 (4.0 g) in water (70 ml).The precipitate that formed was filtered off, washed withwater, dried, and recrystallized from a 5:1 mixture of2-PrOH-DMF.<\/p>\n

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.<\/p>\n","protected":false},"excerpt":{"rendered":"
