Reaction Steps

3-Amino-6-(6-methoxy-3-pyridyl)-5-phenyl-2-pyrazinecarbonitrile (100 mg) was dissolved in 30% hydrogen bromide solution in ACOH (1 ml). The solution was stirred at 25-30° C. for 3 hours. To the solution was added water. The pH of the aqueous mixture was adjusted to 6-7 with 12% aq. NaOH. The crystals were precipitated. The suspension was stirred at 25-30° C. for 3 hours, and stood for 10 hours in refrigerator. The crystals was collected by filtration and dried in vacuo, to give 3-amino-6-(6-methoxy-3-pyridyl)-5-phenyl-2-pyrazinecarboxamide (92.5 mg).
