Reaction Steps

To a solution of 5-bromo-4-ethoxy-2-fluoro-benzonitrile (2 g, 8.2 mmol) in 16.5 mL of dioxane was added dimethylamine (16.5 mL, 33 mmol, 2.0 M in tetrahydrofuran). The reaction was stirred at 80° C. overnight. The reaction mixture was concentrated in vacuo. Purification of the crude residue by flash column chromatography (silica gel, eluting with a gradient of ethyl acetate in hexanes) gave 5-bromo-2-dimethylamino-4-ethoxy-benzonitrile (1.95 g, 88%). LC-MS: 269.2 [(M+H)+].
