実験手順

A mixture of [6-[2-[methyl-[(2-methylpropan-2-yl)oxycarbonyl]amino]propanoylamino]-2-[2-tri(propan-2-yl)silylethynyl]pyridin-3-yl]boronic acid D1a (1.5 g, 3.0 mmol), 3-iodo-7-methyl-2-pyridin-4-ylimidazo[1,2-a]pyridine Za (1.3 g, 3.9 mmol), Na2CO3 (0.95 g, 8.9 mmol), Dichlorobis(triphenylphosphine)palladium(II) (209 mg, 0.3 mmol), dioxane (30 ml) and water (5 ml) is stirred under argon atmosphere for 17 h at 70° C. The mixture is diluted with water and extracted with DCM. The combined organic layers are dried over MgSO4 and concentrated in vacuo. The product is purified by RP HPLC. Yield: 965 mg (49%). HPLC-MS: M+H=667; tR=2.04 min (*Method—3).
