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. 288-13-1, name is 1H-Pyrazole, A new synthetic method of this compound is introduced below., Recommanded Product: 288-13-1
General procedure: In a 50 mL round-bottom flask, pyrrole or pyrazole or indole(2.0 mM), 4-iodonitrobenzene (4.4 mM, 1.2 equiv.), Pd(PPh3)4 (2.5mol%) and K2CO3(2.2 equiv.) were added under continuous stirring condition. To this, 5.0 mL of dry DMA was then added under reflux condition at 110 C for 20 h. After completion of the reaction (monitored by thin-layer chromatography), the reaction mixture was allowed to cool at room temperature and diluted with distilled water. After that the solution was extracted with ethyl acetate and the organic layer was dried over anhydrous MgSO4, which was subjected to column chromatography to obtain the corresponding products.
The synthetic route of 288-13-1 has been constantly updated, and we look forward to future research findings.
