Carbon tetrabromide → 2-(Bromomethyl)-1-benzofuran

Participants

Reaction Steps

A solution of benzofuran-2-ylmethanol (120 mg; 0.81 mmol) in anh. DCM (5 ml) was treated at rt with CBr4 (268 mg; 0.81 mmol), and with PPh3 (212 mg; 0.81 mmol). The resulting mixture was further stirred at rt, under nitrogen, for 17 h. Concentration to dryness under reduced pressure, and subsequent purification by FC (DCM) afforded 2-(bromomethyl)benzofuran as a yellow oil (128 mg; 75%) which was directly used for the next reaction.
