反应详情

To methanol (0.28 mL, 6.9 mmol) and 4-bromo-2,6-difluorobenzonitrile (1500 mg, 6.88 mmol) in THF (34 mL) was added NaHMDS (6.88 mL, 1.0 M in THF, 6.88 mmol) at 0° C. The reaction mixture was stirred at rt overnight, and diluted with brine, extracted with EtOAc. The organic layer was dried, and evaporated. The crude product was purified by column chromatography (0-30% EtOAc/Hex) to give 4-bromo-2-fluoro-6-methoxybenzonitrile.
