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. 22236-08-4, name is 3-(Difluoromethoxy)aniline, A new synthetic method of this compound is introduced below., Computed Properties of C7H7F2NO
0.429 g of 3-(difluoromethoxy)-aniline (2.7 mmol) were dissolved in 5 mL of pyridine. 1 g of 4-methyl-3-[4-(2,2,2-trifluoro-acetyl)-piperazin-1-yl]-benzenesulfonylchloride (2.7 mmol) were added slowly at room temperature. After stirring for 16 h at room temperature, the reaction mixture was evaporated several times after addition of toluene. The residue was dissolved in dichloromethane and washed several times with 5% aqueous ammonium chloride. The organic phase was then washed with saturated aqueous sodium chloride, dried over sodium sulphate, filtered, and the solvent evaporated. The crude product was purified via silica gel chromatography using dichloromethane/methanol (0-5%) to yield 0.63 g of product.
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.
