Reaction Steps

A solution of 3-amino-6-bromo-pyrazine-2-carbonitrile (1 g, 5.025 mmol) in MeOH (20 mL) was cooled to 0° C. and treated with hydroxylamine hydrochloride (349.2 mg, 5.025 mmol) and triethylamine (508.5 mg, 700.4 μL, 5.025 mmol) and the reaction allowed to warm to ambient temperature. After a period of 2 hours a precipitate was observed which was filtered off. The resultant filtrate was evaporated to dryness and triturated with MeOH to furnish further product as a beige solid (771 mg, 78% Yield).
