3-Aminopyridin-4-ol Use and Manufacturing

Step 2: a) 4-Hydroxy-3-nitropyridine (2.8 g, 20.0 mmol) was dissolved in 150 mL of methanol and 280 mg of Pd/C was added.The air in the reaction flask was replaced with hydrogen, and hydrogen was continuously introduced, stirred at room temperature, and monitored by TLC until the reaction was completed.The reaction mixture was filtered under suction, the cake was washed with methanol, and the filtrate was collected and concentrated under reduced pressure.3-amino-4-hydroxypyridine obtained as a dark orange oily liquid(1.98g, 90percent).
