Reaction Steps
3-chloro-6-(5-chloro-2-fluoropyridin-4-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)pyrazin-2-amine (0.0342 g, 0.096 mmol), CuCN (0.034 g, 0.383 mmol), and dppf (0.085 g, 0.153 mmol) were dissolved in dioxane (1.5 ml). The solution was then degassed by sparging with argon for 5 min. It was then treated with Pd2(dba)3 (0.035 g, 0.038 mmol). The reaction mixture was then heated at 100° C. for 5 hr. The reaction mixture was filtered through a pad of Celite then it was concentrated in vacuo to give 0.110 g of 5-(5-chloro-2-fluoropyridin-4-yl)-3-((tetrahydro-2H-pyran-4-yl)methyl)aminopyrazine-2-carboxamide. LCMS (m/z): 366 (MH+), retention time=0.89 min.
