Procedure

The subtitle compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of azetidine-1-sulfonamide (prepared according to patent WO 2004/011443, 0.22 g), tris(dibenzylideneacetone)dipalladium (0) (97 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (50 mg), cesium carbonate (0.52 g) and 4-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-[(2,2,5-trimethyl-1,3-dioxan-5-yl)oxy]-pyrimidine (0.44 g) in dioxane (10 mL). Purification was by column chromatography on silica gel using EtOAc/isohexane (2:8 to 3:7 gradient) as eluent to give the subtitle compound as a pale yellow oil. Yield: 0.46 g
