N-cyclopropyl-3-nitro-1H-pyrazole-5-carboxamide (1.0 g, 5.10 mmol) and platinum (iv) oxide (0.116 g, 0.510 mmol) in ethanol were hydrogenated at 50 psi for 2 hours. The reaction mixture was filtrated through Celite and the filtrate was concentrated to give 0.916 g of 3-amino-N-cyclopropyl-1H-pyrazole-5-carboxamide as a solid. The crude was used without purification. MS (ESI) m/z 167.1 (M+H).
