Reaction Steps

To a solution of 5-(3-nitropyrazol-1-yl)valeronitrile (9.16 g.) in dry tetrahydrofuran (200 ml.) was added 5% w/w palladium on carbon (1.8 g.). The mixture was stirred at 20° under an atmosphere of hydrogen. 3.2 Liters of hydrogen were absorbed over 4 hours. The catalyst was filtered off and the filtrate was evaporated in vacuo to give 5-(3-aminopyrazol-1-yl)valeronitrile as an oil.
