PROCEDURE
实验过程
Following Example 156g, 200b (350 mg, 2 mmol), 3,5-dibromo-1-methyl-1H-pyridin-2-one (0.54 g, 2 mmol), cesium carbonate (1.3 g, 4 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.18 g, 0.2 mmol), Xantphos (0.23 g, 0.4 mmol) and 1,4-dioxane (20 mL) were heated at 100° C. for 8 hours. Work-up and flash column chromatography (silica, 3:1 methylene chloride/methanol) give a 98% yield (0.69 g) of 3-(5-(azetidin-1-ylmethyl)-1-methyl-1H-pyrazol-3-ylamino)-5-bromo-1-methylpyridin-2(1H)-one 200c as a yellow solid. MS (ESI+) m/z 354.1 (M+H).
