Introduction of a new synthetic route about 4-Bromo-3-fluoroanisole

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Bromo-3-fluoroanisole, other downstream synthetic routes, hurry up and to see.

458-50-4, A common compound: 458-50-4, name is 4-Bromo-3-fluoroanisole, belongs to ethers-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.

General procedure: To a solution of 2-bromo-4-fluorobenzonitrile (0.30 g, 1.5 mmol) and cyclopropanol (0.14 g, 2.4 mmol) in DMF (4 mL) wasadded Cs2CO3 (0.88 g, 2.7 mmol) in a 25 mL single-necked round-bottom flask. After that, themixture was stirred at 25 ¡ãC under nitrogen. After stirring for 4 h, the resulting mixture was dilutedwith H2O (30 mL) and extracted with MTBE (10 mL¡Á3). Then the combined organic phase waswashed with saturated aqueous NaCl (10 mL¡Á3) and dried over Na2SO4 for 0.5 h. After that, theorganic phase was filtered under reduced pressure and the filtrate was concentrated underreduced pressure to give product as a yellow sticky substance. Then a mixture of 30 mL MTBE and100 mL n-hexane was added to dissolve the yellow sticky substance. Subsequently, the solutionwas cooled for 30 minutes with the mixture of water and ethanol. Lastly, the solution was filteredunder reduced pressure and the filtrate was dried naturally to obtain desired product in 80.3percentyield (0.29g).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Bromo-3-fluoroanisole, other downstream synthetic routes, hurry up and to see.
