실험 절차

To a stirred solution of methyl 3-amino-6-[4-(dimethylcarbamoyl)phenyl]pyrazine-2-carboxylate (1.7011 g, 5.664 mmol) in EtOH (10.21 mL) was added hydrazine (726.1 mg, 711.2 μL, 22.66 mmol). The resultant solution was heated to reflux for 30 minutes and then allowed to cool to RT. The precipitate was filtered off and dried (1.47 g, 87% Yield). 1H NMR (400.0 MHz, DMSO) d 2.96 (s, 3H), 3.00 (s, 3H), 4.58 (d, J=4.4 Hz, 2H), 7.46 (d, J=8.4 Hz, 2H), 8.27-8.29 (m, 2H), 8.88 (s, 1H) and 10.09 (s, 1H) ppm; MS (ES+) 301.13
