실험 절차
A solution of 2-(ethylamino)-3-nitropyridine (52 g) in MeOH (600 mL) was stirred overnight at room temperature under hydrogen (1 atm.) in the presence of 20% Pd(OH)2/C (10.4 g). The catalyst was removed by filtration through diatomaceous earth. The filtrate was concentrated under reduced pressure to give the title compound as a black solid (39 g, 88% yield over steps a) and b).
