실험 절차

A solution comprising 2-nitro-1,4-phenylenediamine (21.0 g, 137 mmol) in ethanol (350 mL) and 4.0M hydrogen chloride in dioxane (30.8 mL, 123 mmol) was stirred at room temperature for 15 minutes and then diethyl ether (1 L) was added to give a precipitate. The precipitate was collected by filtration, washed with additional diethyl ether and dried in vacuo to provide 2-nitro-1,4-phenylenediamine hydrochloride (23.3 g, 100% yield).
