実験手順

Intermediate 156g was synthesized using the same procedure as Example 112a, except using 156f (360 mg, 1.78 mmol), 3,5-dibromo-1-methyl-1H-pyridin-2-one (0.43 g, 1.6 mmol), cesium carbonate (1.56 g, 4.8 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.15 g, 0.16 mmol), Xantphos (0.18 g, 0.32 mmol) and 1,4-dioxane (18 mL). The reaction mixture was heated at 115° C. for 24 hours. Work-up and flash column chromatography (silica, 60:35:5 methylene chloride/diethyl ether/methanol) give 38% yield (0.23 g) of 156g as a green solid: MS (ESI+) m/z 390.1 (M+H).
