Reaction Steps

Commercially available 2-amino-4-methyl-3nitropyridine (10.0 g, 65.3 mmol) was suspended in ethanol (450 mL) and the flask was filled with argon. 10% palladium carbon (13.9 g, 50% water-containing) was added to the mixture and stirred at room temperature overnight under the flow of hydrogen. Solids were filtered through Celite and this was washed with ethanol. The filtrate was concentrated under reduced pressure to obtain Compound P12 (7.81 g, 63.3 mmol, 97%).
