Participants

Reaction Steps

1-(Bromomethyl)-4-nitrobenzene (1.08 g, 5.00 mmol) was added to a vigorously stirred mixture of tert-butyl piperazine-1-carboxylate (1.02 g, 5.50 mmol) and sodium carbonate (0.583 g, 5.50 mmol) in DMF (5 mL) at room temperature and the resulting mixture stirred for two hours. Water (25 mL) was added, and the resulting suspension was allowed to stand for five minutes then filtered. The collected solid was washed with water (25 mL) and air-dried to give the title compound (I92) (1.523 g, 95% yield);
