実験手順

In a 100 mL round bottom flask was charged N-ethyl-2-methyl-2-(4-nitrophenyl)propan-1-amine (1.50 g, 6.75 mmol), anhydrous acetonitrile (22 mL), ethyl iodide (1.16 mL, 7.43 mmol), and potassium carbonate (1.87 g, 13.5 mmol). The reaction was brought to reflux for 4 h. The reaction mixture was filtered and concentrated in vacuo. The residue was diluted with water and ethyl acetate and layers were separated. The organic layer was washed with once each with water, and then with brine, dried over sodium sulfate, filtered and concentrated in vacuo to give N,N-diethyl-2-methyl-2-(4-nitrophenyl)propan-1-amine (1.45 g, 86.1%). LC/MS (ESI+) 251 (M+H)+.
