Reaction Steps
Potassium 2-methylpropan-2-olate (4.214 g, 35.678 mmol) was slowly added under an atmosphere of dry N2 to a solution of 2-chloro-4-nitropyridine (5.142 g, 32.434 mmol) in 2-methoxyethanol (40.0 mL, 506.74 mmol). The reaction was stirred at ambient temperature for 2 hours and then concentrated under reduced pressure. The resulting oil was diluted with water (200 mL) and extracted with EtOAc. The combined organic phases were dried over Na2SO4, filtered and concentrated under reduced pressure to give 5.36 g (88%) of desired product as a colorless oil.
