Reaction Steps

A mixture of 1-benzyl-4-nitro-1H-pyrazole (33 mg, 0.162 mmol) and 10% Pd/C (10 mg) was stirred under an hydrogen atmosphere at rt for 12 h. The catalyst was filtered off, washed with methanol and the solvent was removed under reduced pressure to give the title compound as dark brown oil (27.4 mg, 97%). MS ISP (m/e): 174.2.3 (100) [(M+H)+].
