Reaction Steps

To a 0° C. solution of 2,6-difluoropyridine (69.6 g, 605 mmol, 1.0 equiv) and isobutyronitrile (41.7 g, 610 mmol, 1.0 equiv) in toluene (500 mL) was added sodium hexamethyldisilazide (2.0 M in THF, 302 mL, 605 mmol, 1.0 equiv) in a dropwise manner. The resulting mixture was allowed to slowly warm to room temperature and stirred overnight. The reaction was then quenched with water (500 mL), and the organic layer was separated from the aqueous layer. The aqueous layer was extracted with EtOAc (2×300 mL), and the combined organic phases were washed with saturated brine solution (2×400 mL), dried over Na2SO4, concentrated to give a crude yellow oil, and chromatographed with silica gel (2-10% EtOAc/hex) to give 2-(6-fluoropyridin-2-yl)-2-methylpropanenitrile (55.7 g, 56%) as a clear oil.
