実験手順

A mixture of tert-butyl-N-[1-[[5-bromo-6-(2-phenylethynyl)pyridin-2-yl]amino]-1-oxopropan-2-yl]-N-methylcarbamate C2a (50 mg, 0.11 mmol), 9-benzyl-9-borabicyclo[3.3.1]-nonane (283 μl, 0.14 mmol) Cs2CO3 (71 mg, 0.22 mmol), 1,1′-Bis(diphenylphosphino)-ferrocene]dichloropalladium(II) (8.0 mg, 0.01 mmol) and dioxane (0.6 ml) is stirred under argon atmosphere for 45 minutes at 70° C. The mixture is concentrated in vacuo and the product purified by RP HPLC. Yield: 26 mg (51%). HPLC-MS: M+H=470; tR=1.97 min (*Method—4).
