実験手順

To an argon flushed pressure vial (15 mL) was added copper (I)iodide (0.0070 g, 0.037 mmol), PdCl2(dppf)-CH2Cl2Adduct (0.012 g, 0.015 mmol), N-((6-chloro-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methyl)-7-methoxy-1,5-naphthyridin-4-amine (0.050 g, 0.15 mmol), and triethyl(ethynyl)silane (0.13 ml, 0.73 mmol) in acetonitrile (2 mL) followed by triethylamine (0.61 ml, 4.4 mmol). The vial was sealed and stirred at room temperature overnight The solution was concentrated and purified by MPLC (eluted with 0-10% (90:10:1 DCM:MeOH:NH4OH)) to yield the product as a light yellow solid. MS m/z=446.1 [M+1]+. Calc'd for C23H27N7OSi: 445.2.
