Reaction Steps
A mixture of (7-fluorobenzofuran-2-yl)methanol (1.38 g, 8.31 mmol), tetrabromomethane (4.41 g, 13.3 mmol) and triphenylphosphine (2.61 g, 9.97 mmol) in dichloromethane (42 mL) was stirred at 0° C. for 2 h and concentrated in vacuo to dryness. The residue was purified by column chromatography (hexanes/ethyl acetate, 49/1) to afford 2-(bromomethyl)-7-fluorobenzofuran (1.85 g, 97%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ7.34-7.29 (m, 1H), 7.20-7.12 (m, 1H), 7.10-7.02 (m, 1H), 6.82-6.77 (m, 1H), 4.60 (s, 2H).
