4-Bromo-1-H-pyrazole (9.4 mmol, 1.38 g), 1,1,1-trifluoro-2-iodo-ethane (28.2 mmol, 2.75 mL), and cesium carbonate (14.1 mmol, 4.58 g) were combined in DMF (10 mL) and stirred at room temperature for overnight. The resulting mixture was subjected to standard aqueous workup to afford the title compound which was used crude in the next step.
