Reaction Steps

Then, a reaction flask was loaded with this 3-methoxy-2-nitropyridine (9.0 g), sodium sulfide enneahydrate (64 g), ethanol (93 ml) and water (46 ml) and they were mixed, followed by stirring at 70° C. for 2.5 hours. Then, the mixture was cooled to room temperature. To this, toluene and water were added, followed by stirring. The organic layer was collected and washed with a saline solution, and then dried with sodium sulfate. This was filtrated and the filtrate was condensed to give 2-amino-3-methoxypyridine (5.1 g).
