실험 절차

A 0.12 g portion of 2-(1-imidazolyl)-4-nitropyridine N-oxide was suspended in 14 ml of 70% ethanol aqueous solution, 0.32 g of iron powder and 20 mg of ammonium chloride were added in that order to the suspension and then the mixture was heated at 100° C. for about 20 minutes. Then, the insoluble matter was immediately removed by filtration, and the resulting filtrate was evaporated under reduced pressure to obtain 0.1 g of the title compound.
