Reaction Steps
To a 300-mL, 3-necked flask equipped with a reflux tube were added 1.52 g (4.00 mmol) of tri(4-nitrophenyl)amine and 5% Pd/C (200 mg), and the inside was replaced with argon. Dioxane (50 mL) and ethanol (25 mL) were added thereto, and the resulting mixture was stirred at a temperature of 80° C., and hydrazine monohydrate (8.0 mL) was added dropwise thereto over 3 hours and further stirred at 80° C. for 20 hours. The catalyst was separated by filtration, and then the reaction mixture was added to ice water (400 mL). The obtained gray solid was obtained by filtration, washed with water and then vacuum-dried, whereby a desired product was obtained (Quantity: 1.02 g, 3.51 mmol, Yield: 88%).
