반응 단계

To a stirred solution of 4-bromo-2-fluoro benzyl bromide (1.5 g, 5.6 mmol) in DMF (50 mL) was added sodium cyanide (0.8 g, 16.8 mmol). The reaction was stirred at 90° C. for 1 h, and cooled at rt. After quenching with brine (50 mL) and diluted with EtOAc (100 mL), the EtOAc layer was washed with brine (50 mL), dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by flash chromatography (silica gel, hexanes:EtOAc 5:1) to afford 4-bromo-2-fluoro benzyl cyanide as yellow solid. MS (ESI) 307 (M+H)+.
