A mixture of 1-(2-(4-nitro-1H-pyrazol-1-yl)ethyl)pyrrolidin-2-one (0.21 g, 0.9 mmol) and Pd/C (50 mg) in ethanol (20 mL) was stirred overnight at room temperature under an atmosphere of hydrogen then filtered over Celite. The filtrate was concentrated in vacuo to afford 1-(2-(4-amino-1H-pyrazol-1-yl)ethyl)pyrrolidin-2-one V-5 (0.19 g, 100%) as a purple oil. LC-MS (Method C), RT=0.38 min. (ES+) 195.
