Reaction Steps

3-amino-6-bromo-pyrazine-2-carbonitrile (4.5958 g, 23.09 mmol) was dissolved in MeOH (91.92 mL), cooled to 0° C. and treated with hydroxylamine hydrochloride (1.605 g, 23.09 mmol) and triethylamine (2.336 g, 3.218 mL, 23.09 mmol). The reaction was allowed to warm to ambient temperature, stirred for 48 hours and then evaporated to dryness. Methanol (a minimum amount) was added, the mixture sonicated, filtered and washed with MeOH to give the product as a brown solid 5.27 g, 98% Yield). 1H NMR (400.0 MHz, DMSO) d 5.88 (s, 2H), 7.64 (br s, 2H), 8.14 (s, 1H) and 10.38 (s, 1H) ppm; MS (ES+) 233.75
