실험 절차
A mixture of (3-methyl-4-nitro-1H-pyrazol-1-yl)acetonitrile (2.6 g, 15.7 mmol), NH4Cl (3.4 g, 62.7 mmol) and Fe powder (3.5 g, 62.7 mmol) in MeOH (60 mL) and water (12 mL) was stirred at 80° C. for 2 days. The mixture was filtered, concentrated and the residue was purified by flash chromatography (MeOH: CH2Cl2 20:1) to give the title compound (440 mg, 15% yield) as brown oil.
