Piperidine → N-(1-(3,4-dimethylphenyl)-1H-pyrazol-3-yl)-2-nitro-5-(piperidin-1-yl)benzamide

Temperatur

110 °C

Into a 50-mL round bottom flask, was placed a solution of 5-chloro-N-(1-(3,4-dimethylphenyl)-1H-pyrazol-3-yl)-2-nitrobenzamide 4g (300 mg, 0.81 mmol, 1.00 equiv) in N,N-dimethylformamide (10 mL), potassium carbonate (330 mg, 2.39 mmol, 3.00 equiv), and piperidine (200 mg, 2.35 mmol, 3.00 equiv). The resulting solution was stirred for 4 h at 110° C. The resulting mixture was concentrated under vacuum. The residue was dissolved in 50 mL of ethyl acetate. The resulting mixture was washed with 2×30 mL of brine, dried over sodium sulfate, and concentrated under vacuum. This resulted in 300 mg (88%) of product as a yellow solid.
