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, 0.17 g), tris(dibenzylideneacetone)dipalladium (0) (78 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (40 mg), cesium carbonate (0.42 g) and 4-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-[1-[(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]-1-methylethoxy]-pyrimidine (0.37 g) in dioxane (8 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: 0.37 g
