40161-54-4, 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. 40161-54-4, name is 1-Bromo-2-fluoro-4-(trifluoromethyl)benzene, A new synthetic method of this compound is introduced below.
General procedure: Benzimidazole (5 mmol), 1-bromo-2-fluorobenzene derivatives (15 mmol, 2 equiv) and tripottasium phosphate (5.31g, 25 mmol, 5 equiv) were dissolved in DMF (30 mL). The mixture was stirred at 150 C. The reaction time was determined by monitoring with TLC. The reaction mixture was diluted with CH2Cl2 (50 mL) and water (50 mL). The phases were separated, and the aqueous layer was extracted with CH2Cl2 (2 ¡Á 30 mL). The combined organic layerswere washed with water (3 ¡Á 50 mL), dried with MgSO4, and concentrated under reduced pressure. The residue was purified by silica gel chromatography (n-hexane/AcOEt).
