To a solution of 5-(azetidin-1-ylmethyl)-1-methyl-3-nitro-1H-pyrazole (349 mg, 1.78 mmol) in ethanol (20 mL) was treated with palladium on carbon (10%, 50 mg). The resulting mixture was stirred under a hydrogen (1 atm) for 48 h. The reaction mixture was filtered through a celite pad, and the pad washed with ethanol. The filtrate was concentrated in vacuo to give 5-(azetidin-1-ylmethyl)-1-methyl-1H-pyrazol-3-amine (292 mg, 99%) as a light yellow oil.
