Reaction Steps
6-(6-(1-(Tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl)pyridin-3-yl)-4-(tetrahydro-2H-pyran-4-yl)-3,4-dihydropyrazino[2,3-b]pyrazin-2(1H)-one. A mixture of 4-(tetrahydro-2H-pyran-4-yl)-6-(trimethylstannyl)-3,4-dihydropyrazino[2,3-b]pyrazin-2(111)-one (1 equiv), 5-bromo-2-(1-(tetrahydro-2H-pyran-2-yl)-1H -1,2,4-triazol-3-yl)pyridine (1.2 equiv), tris(dibenzylideneacetone)dipalladium (0.1 equiv), tri-o-tolylphosphine (0.2 equiv), triethylamine (3 equiv) and N,N-dimethylformamide was heated at 95° C. for 3 h under nitrogen. Concentration and chromatography purification give the desired product in 39% yield. MS (ESI) m/z 463.1 [M+1]+.
