Reaction Conditions:
with potassium carbonate in propan-2-one at 45;Reflux;
Steps:
Step a: Preparation of 1-ethyl-4-(4-nitrobenzyl)piperazine (M-1)
4-Nitrobenzyl chloride (7.00 g, 40.80 mmol) was dissolved in acetone (100 mL), N-ethylpiperazine (5.59 g, 48.96 mmol) and potassium carbonate (11.28 g, 81.59 mmol) were added, and the temperature was raised to 45°C The reaction was refluxed overnight. The next day, the reaction was complete by TLC monitoring.The heating and stirring were stopped, and the filtrate was obtained through diatomite-assisted filtration, and the filtrate was concentrated under reduced pressure to obtain a brown liquid.The crude product was recrystallized from ethyl acetate to give M-1 as a yellow solid (9.50 g, 93.5%).
