Synthetic Route of 363-51-9,Some common heterocyclic compound, 363-51-9, name is 2-Chloro-6-fluoroaniline, molecular formula is C6H5ClFN, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
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 synthetic route of 363-51-9 has been constantly updated, and we look forward to future research findings.
