Reaction Conditions

Reaction Steps

A 60% dispersion of sodium hydride in mineral oil (450 mg, 11.25 mmol) was suspended in anhydrous tetrahydrofuran (10 mL). The suspension was cooled to 0° C. and 1,1,1,3,3,3-hexafluoropropan-2-ol (1.74 g, 10.35 mmol) was added over 15 minutes. The suspension was stirred 30 minutes and 2,3-dichloro-5-nitropyridine (1.50 g, 7.77 mmol) was added portionwise. The reaction was stirred at room temperature overnight then concentrated in vacuo. The crude residue was partitioned between ethyl acetate (50 mL) and water (50 mL). The aqueous layer was extracted by ethyl acetate (2×25 mL). Organic layers were combined, dried over magnesium sulfate, and concentrated in vacuo to afford the title compound as an orange oil (2.55 g, 100%).
