Reaktionsschritte

A solution of (4-(2-fluoroethoxy)phenyl)methanol (117 mg; 0.68 mmol) in anh. DCM (5 ml) was treated at rt with CBr4 (228 mg; 0.68 mmol), and with PPh3 (180 mg; 0.68 mmol). The resulting mixture was further stirred at rt, under nitrogen, for 1 h. Concentration to dryness under reduced pressure, and subsequent purification by FC (DCM) afforded 1-(bromomethyl)-4-(2-fluoroethoxy)benzene as a slightly yellow oil which was directly used for the next reaction.
