2,2,2-Trifluoroethanol → HCID 59570383, compound

Participants

Reaction Steps

To a solution of potassium tert-butoxide (0.45 g, 4.02 mmol) in tetrahydrofuran (8 mL) is added 2,2,2-trifluoroethanol (0.27 mL, 3.69 mmol), and the mixture is stirred at room temperature for 20 minutes. A solution of 4-nitropicolinonitrile (0.50 g, 3.35 mmol) in tetrahydrofuran (8 mL) is added dropwise the mixture, and the resulting mixture is stirred at room temperature for 20 minutes. The reaction mixture is poured into saturated aqueous ammonium chloride solution (20 mL) and extracted with ethyl acetate (30 mL). The organic layer is dried over sodium sulfate and concentrated in vacuo to give 0.71 g (>99% yield) of the title compound as yellow oil. This material is used for the next reaction (Step-2) without further purification.
