실험 절차

A mixture of azetidine-1-sulphonamide (420 mg), tris(dibenzylideneacetone)dipalladium (0) (71 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (37 mg), cesium carbonate (380 mg) and 4-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-[(2-phenyl-1,3-dioxan-5-yl)oxy]-pyrimidine (350 mg) in anhydrous dioxane (8 ml) was heated to reflux in a microwave at 100° C., 300 W, open vessel with cooling for 10 minutes. The reaction mixture was diluted with methylene chloride, filtered through arbocel and the filtrate evaporated. The residue was purified by column chromatography on silica using a 80:20 to 70:30 mixture of iso-hexane and ethyl acetate as eluent to give the sub-title compound as a white solid.
