실험 절차

2-Bromo-5-nitropyridine (0.3 g, 1.48 mmol) was treated with piperazine (0.64 g, 7.89 mmol) in tetrahydrofuran (4 ml) and the reaction mixture was stirred for 30 minutes. Subsequently the reaction mixture was poured onto ice-cold water (25 ml) and extracted with ethyl acetate (25 ml). The organic layer was washed with brine and evaporated to furnish the product.
