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, 0.25 g), tris(dibenzylideneacetone)dipalladium (0) (83 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (43 mg), cesium carbonate (0.44 g) and 4-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-[(2S)-1,4-dioxaspiro[4.5]dec-2-ylmethoxy]-pyrimidine (0.40 g) in dioxane (8 mL). Purification was by column chromatography on silica gel using EtOAC/isohexane (1:9 to 1:2 gradient) as eluent to give the subtitle compound as a pale yellow oil. Yield: 0.34 g
