4-Bromobenzyl alcohol → 1-BroMo-4-(fluoroMethyl)-benzene

Participants

Reaction Steps

To a solution of 4-bromobenzylalcohol (561 mg) in methylene chloride (3 mL) was added [bis-(2-methoxyethyl)amino]sulfur trifluoride (590 μL) over a period of 5 minutes under ice-cooling and the mixture was stirred at the same temperature for 1 hours and then stirred at room temperature for 1 hour. The reaction mixture was concentrated in vacuo and the resultant crude product was purified by a column chromatography on silica gel (solvent; hexane/ethyl acetate=100:0→95:5) to give 1-bromo-4-fluoromethyl-benzene (340 mg, yield: 60%).
