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. 2924-09-6, name is 5-Bromo-2-fluoroaniline, A new synthetic method of this compound is introduced below., Product Details of 2924-09-6
General procedure: A Schlenk tube was charged with Oxone (0.398 g, 0.648mmol) and trifloroacetic acid (0.099 mL, 1.296 mmol) in anhydrous dioxane (2 mL) under argon. To this mixture was added 2-fluoroaniline (0.06 g, 0.54 mmol), and the reaction mixture was heated to 90 C under argon until starting material was consumed. As the reaction progressed, the color turned from lightred to dark red. The mixture was then cooled to room temperature and washed with a saturated aqueous sodium bicarbonate.The mixture was extracted with EtOAc (2 × 20 mL) and the combined organic layers were dried over Na2SO4. After filtering andremoval of the solvent under reduced pressure in vacuo, theresidue was purified by silica gel (100-200 mesh) column chromatography(hexane-EtOAc, 9:1), to afford a pale-brown solid(65%) of 2-hydroxy-N-trifluoroacetanilides from 2-fluoroaniline(2a).
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.
