How is 3-nitropyridin-2-amine (CAS: 4214-75-9) typically synthesized?

3-nitropyridin-2-amine can be synthesized via a multi-step process. Common methods include the reduction of 3-nitropyridine with a suitable reducing agent such as sodium borohydride. The overall reaction involves the formation of the amine from the nitro group, and the process typically achieves a yield of around 70-80%. Catalysts such as palladium on carbon can be used to improve the efficiency of the reduction.
