Reaction Steps
To a 0° C. solution of 2-chloro-3-fluoropyridine (3.0 g, 23 mmol, 1.0 equiv) and acetonitrile (1.3 mL, 25 mmol, 1.1 equiv) in toluene (50 mL) was added sodium hexamethyldisilazide (NaHMDS) (2.0 M in THF, 13 mL, 25 mmol, 1.1 equiv). The resulting mixture was stirred for 2 hours at 0° C. and then partitioned between EtOAc and water. The aqueous layer was extracted with EtOAc and the combined organic phases were washed with saturated NaCl, dried over Na2SO4 and concentrated in vacuo to provide the crude desired product as an oil which was used without further purification.
