YieldReaction ConditionsOperation in experiment
30% In N-methyl-acetamide; hexane; ethyl acetate; Example 297B 5-[3,5-bis(trifluoromethyl)-1H-pyrazol-1-yl]-2-nitropyridine To a cold slurry (0° C.) of sodium hydride (95percent, 439 mg, 18.30 mmol) in dimethylformamide 3.0 mL) was added 3,5-bis(trifluoromethyl)pyrazole (2.50 g, 12.30 mmol). The resulting suspension was stirred for 30 minutes. A solution of <strong>[52092-47-4]5-chloro-2-nitropyridine</strong> (1.90 g, 12.00 mmol) was added. The resulting mixture was heated at reflux for 24 hours, then cooled to room temperature. The mixture was poured into saturated sodium chloride solution (100 mL). The aqueous mixture was extracted with ethyl acetate (3*100 mL) and the combined organic layers were dried over sodium sulfate, filtered and concentrated. The residue was purified by flash column chromatography using 20percent ethyl acetate/hexane to afford a yellow oil (1.17 g, 30percent yield). MS (DCI/NH3) nme 297 (M+1 for aniline)+; 1H NMR (DMSO-d6, 300 MHz) delta9.38 (d, 1H), 8.88 (dd, 1H), 8.21 (d, 1H), 8.02 (s, 1H).
