Reaction Steps

7-Bromo-1-(3-methoxybenzyl)-3,4-dihydropyrazino[2,3-b]pyrazin-2(1H)-one. Methyl 2-(3,5-dibromopyrazin-2-ylamino) acetate (0.58 g, 1.8 mmol), 3-methoxybenzylamine (227 μL, 1.8 mmol), diisopropylethylamine (1 mL), and dimethylsulfoxide (1 mL) were heated to 100° C. for 3 d under nitrogen. The reaction was extracted with ethyl acetate and water. The organic layer was dried with magnesium sulfate, filtered and concentrated. The residue was purified on silica gel column (0-100% ethyl acetate in hexanes) to give the title compound (124 mg, 20% yield) as a pink solid. MS (ESI) m/z 349.0 [M+1]+.
