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. 19968-17-3, name is 4-Bromo-3-(trifluoromethyl)-1H-pyrazole, A new synthetic method of this compound is introduced below., COA of Formula: C4H2BrF3N2<\/a><\/p>\n

To a solution of 4-bromo-3- (trifluoromethyl) -1H-pyrazole (1.01 g, 4.7 mmol) in DMF (40 mL)2- (bromineMethyl) pyridine hydrobromide (1.76 g, 6.96 mmol), Cs2CO3 (5.3 g, 16 mmol) and KI (0.4 g, 2 mmol)100 for 10h. The reaction mixture was concentrated under reduced pressure to remove DMF, extracted with water (40 mL) and extracted with methylene chloride (50 mL \u00a1\u00c1 3), and then the organicThe phases were dried over anhydrous Na2SO4. The concentrated crude product was isolated by silica gel column chromatography (eluent: PE \/ EtOAc (v \/ v) = 1 \/1) to give 1.2 g of a yellow oil, yield: 83%.<\/p>\n
