Reaction Steps

The subtitle compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 5-(aminosulfonyl)-N-(tert-butyl)-2-furamide (0.25 g), tris(dibenzylideneacetone)dipalladium (0) (58 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (30 mg), cesium carbonate (0.65 g) and 2-[[6-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-4-pyrimidinyl]oxy]-(2R)-propanoic acid ethyl ester (product of Example 11 step i) (0.26 g) in dioxane (10 mL). Purification was trituration with Et2O to give the subtitle compound as a white solid. Yield: 0.25 g
