4-((cis)-4-Methoxycyclohexyl)-6-(2-methyl-6-(4-(tetrahydro-2H-pyran-2-yl)-4H-1,2,4-triazol-3-yl)pyridin-3-yl)-3,4-dihydropyrazino[2,3-b]pyrazin-2(1H)-one. 4-((cis)-4-Methoxycyclohexyl)-6-(trimethylstannyl)-3,4-dihydropyrazino[2,3-b]pyrazin-2(1H)-one 0.292 g, 0.687 mmol), 3-bromo-2-methyl-6-(1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl)pyridine (0.244 g, 0.756 mmol), tris(dibenzylideneacetone)dipalladium (0.063 g, 0.069 mmol), tri-o-tolylphosphine (0.042 g, 0.137 mmol), triethylamine (0.287 mL, 2.061 mmol) and dimethylformamide (5.0 mL) were combined in a screw capped flask and heated to 95° C. for 1 h. The solution was condensed under reduced pressure and purified using Biotage chromatography (0-80% ethyl acetate in hexanes followed by 0-10% methanol in ethyl acetate) to afford the title compound (0.279 g, 0.687 mmol, 80% yield). MS (ESI) m/z 505.6 [M+1]+.
