Reaction Steps

A solution of N-(2-hydroxy-2-methylpropyl)-N,1-dimethyl-4-nitro-1H-pyrazole-3-carboxamide (1.2 g, 4.7 mmol) in ethanol (30 ml) was flushed with argon and treated with palladium on carbon 10% (120 mg, 1.13 mmol). The reaction mixture was evacuated and flushed with hydrogen and stirred at ambient temperature for 16 h. The reaction mixture was filtered, washed with ethanol and concentrated in vacuo to yield the product as dark red oil (1.0 g, 80%) which was used without any further purification.
