実験手順
6-(Methyloxy)-3-nitro-2-pyridinamine (26 g, 129 mmol) was suspended in EtOH (500 ml) at room temperature under argon and then treated with palladium on carbon (15 g, 14.10 mmol) (10% paste). The reaction was stirred under 1 atmosphere of hydrogen overnight. The reaction was filtered through a Celite pad and the pad washed with EtOH (500 ml). EtOH was evaporated to afford the product as a purple oil (20.68 g, slightly impure).
