Reaction Steps
Methyl 3-amino-6-(3-pyridyl)pyrazine-2-carboxylate (2 g, 8.687 mmol) was heated in hydrazine (1.392 g, 1.363 mL, 43.43 mmol) with a minimal amount of MeOH (5 mL) added at 80° C. for 2 hours. The reaction was treated with water and the product collected by filtration, washed with methanol and dried to give the desired product as a brown solid (1.17 g, 58% Yield). 1H NMR (400.0 MHz, DMSO) d 7.43 (1H, m), 7.47 (2H, br s), 8.54 (2H, m), 8.90 (1H, s), 9.38 (1H, m), 10.16 (1H, br s); MS (ES+) 231.96
