Reaction Steps

2-(Trifluoromethyl)benzoyl chloride (2.0 mL, 11.0 mmol) was added slowly to a solution of 1-(5-nitropyridin-2-yl)piperazine (2.0 g, 10 mmol) and diisopropylethylamine (3.5 mL, 20 mmol) in Dichloromethane (15 mL) at 0° C. under argon. The mixture was then stirred at 25° C. for 2 h. The reaction was quenched with H2O. The aqueous phase was extracted with ethyl acetate. The organic phase was washed with saturated NaCl and dried over anhydrous MgSO4. The organic phase was concentrated and then purified by column chromatography to yield [4-(5-nitropyridin-2-yl)piperazin-1-yl]-(2-trifluoromethylphenyl)methanone as a yellow solid (1.55 g, 41% yield). MS (ES+) m/z 381.1 (M+1).
