2-Amino-6-methoxy-3-nitropyridine → 2,3-Diamino-6-methoxypyridine

Participants

Reaction Steps

6-(Methyloxy)-3-nitro-2-pyridinamine (26 g, 129 mmol) was suspended in ethanol (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 atm of hydrogen overnight. The reaction was filtered through a Celite pad and the pad washed with ethanol (500 ml). Ethanol was evaporated to afford the product as a purple oil (20.68 g, slightly impure).
