N,N,2-trimethyl-1-(3-nitro-1H-pyrazol-1-yl)propan-2-amine (70.6 mg) was dissolved in a mixed solution (ethanol-ethyl acetate, 4:1, 5 mL). Then, 10% palladium-carbon (7 mg) was added to the prepared solution, and the solution was subjected to catalytic reduction at 101 kPa for about 2 hours. The reaction mixture was filtrated through Celite, and the filtrate was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (silica gel NH, ethyl acetate:hexane=1:1) to give the title compound as a yellow oil (56.8 mg, yield: 94%).
