Procedure

The subtitle compound was prepared according to the procedure outlined in example 1, step iv) using a mixture of 1-pyrrolidinesulfonamide (prepared according to patent WO 2004/011443, 0.19 g), tris(dibenzylideneacetone)dipalladium (0) (71 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (52 mg), cesium carbonate (0.38 g), 2-[[6-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-4-pyrimidinyl]oxy]-(2R)-propanoic acid ethyl ester (the product of Example 23 step i) (0.30 g) and dioxane (10 mL). Purification was by column chromatography on silica gel using EtOAc/isohexane (1:1) as eluent to give the subtitle compound as an oil. Yield: 0.38 g
