Reaction Steps
To a solution of 4-bromo-2,6-difluoro-benzonitrile (15.0 g, 68.8 mmol) in tetrahydrofuran (150 ml) is added sodium methoxide (4.5 g, 82.6 mmol) at room temperature and the mixture is stirred for 16 h. The reaction mixture is concentrated under reduced pressure and the resulting solid is purified by column chromatography (silica gel, 5% ethyl acetate/hexane) to obtain 4-bromo-2-fluoro-6-methoxy-benzonitrile (8.5 g, 36.9 mmol, 53%).
