Reaction Steps

To a solution of 4-(trifluoromethyl)-1H-pyrazole (1.0 g, 7.0 mmol) and 4-fluoro-2-methylbenzonitrile (1.16 g, 8.50 mmol) in acetonitrile (8 mL) was slowly added potassium carbonate (1.96 g, 14.2 mmol) at room temperature. The reaction was heated to 80° C. and stirred overnight. The reaction was cooled to room temperature and poured into water. The layers were separated and the aqueous was extracted with ethyl acetate (3×15 mL). The combined organics were washed with water, dried over sodium sulfate, filtered, and concentrated. Purification by flash column chromatography gave 2-methyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)benzonitrile (710 mg, 40%) as a yellow solid. 1H NMR (400 MHz, CDCl3, δ): 8.26 (s, 1H), 7.94 (s, 1H), 7.72-7.74 (m, 2H), 7.61-7.64 (m, 1H), 2.64 (s, 3H).
