実験手順

The title compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of azetidine-1-sulphonamide (prepared according to patent WO 2004/011443, 0.11 g), tris(dibenzylideneacetone)dipalladium (0) (0.10 g), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (60 mg), cesium carbonate (0.26 g), 4-chloro-6-(difluoromethoxy)-2-[[(2,3-difluorophenyl)methyl]thio]-pyrimidine (product of step (0.18 g) and anhydrous dioxane (5 mL). Purification was by column chromatography on silica gel using EtOAc/isohexane (3:7) as eluent and the relevant fractions were evaporated. The resulting oil was triturated with diethyl ether/iso-hexane to give the title compound as a white solid. Yield: 70 mg
