実験手順: A mixture of azetidine-1-sulfonamide (0.27 g), tris(dibenzylideneacetone)dipalladium (0) (50 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (50 mg), cesium carbonate (0.43 g) and (trans)-2-{6-chloro-2-[(2,3-difluorobenzyl)thio]pyrimidin-4-yl}cyclopentanol (the product from step i), 0.50 g) in dioxane (20 ml) was heated at reflux in a microwave at 100° C., 300 W, open vessel with cooling for 1 h. The reaction mixture was then reduced in vacuo and the residue partitioned between DCM (150 ml) and H2O (150 ml). The organics were separated and the aqueous layer was re-extracted with DCM (2×150 ml). Organics were combined, dried (MgSO4) and reduced under vacuo and the resulting residue purified by prep HPLC to give the title compound as a white solid. Yield 74 mg was heated 300 W, open vessel with cooling for 1 h the residue partitioned between DCM (150 ml) and H2O (150 ml) The organics were separated the aqueous layer was re-extracted with DCM (2×150 ml) dried (MgSO4) the resulting residue purified by prep HPLC

実験手順: A mixture of azetidine-1-sulfonamide (0.327 g), tris(dibenzylideneacetone)dipalladium (0) (50 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (50 mg), cesium carbonate (0.585 g) and 4-chloro-2-[(2,3-difluorobenzyl)thio]-6-isopropoxypyrimidine (the product from step i), 0.400 g) in dioxane (20 ml) was heated at reflux in a microwave at 100° C., 300 W, open vessel with cooling for 30 mins. The reaction mixture was then reduced in vacuo and the residue separated between DCM (150 ml) and H2O (150 ml). The organics were separated and the aqueous layer was re-extracted with DCM (2×150 ml). Organics were combined, dried (MgSO4) and reduced in vacuo and the resulting residue purified by prep HPLC to give the title compound as a white solid. Yield: 0.18 g was heated 300 W, open vessel with cooling for 30 mins the residue separated between DCM (150 ml) and H2O (150 ml) The organics were separated the aqueous layer was re-extracted with DCM (2×150 ml) dried (MgSO4) the resulting residue purified by prep HPLC

実験手順: A mixture of azetidine-1-sulfonamide (0.33 g, prepared according to patent WO2004/011443), tris(dibenzylideneacetone)dipalladium (0) (50 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (50 mg), cesium carbonate (0.585 g) and 2-({6-chloro-2-[(2,3-difluorobenzyl)thio]pyrimidin-4-yl}oxy)ethanol ((the product from example 112 step ii), 0.400 g) in dioxane (20 ml) was heated at reflux in a microwave at 100° C., 300 W, open vessel with cooling for 30 mins. The reaction mixture was then reduced in vacuo and the residue separated between DCM (150 ml) and H2O (150 ml). The organics were separated and the aqueous layer was re-extracted with DCM (2×150 ml). Organics were combined, dried (MgSO4) and reduced in vacuo and the resulting residue purified by prep HPLC to give the title compound as a white solid. Yield: 0.13 g was heated 300 W, open vessel with cooling for 30 mins the residue separated between DCM (150 ml) and H2O (150 ml) The organics were separated the aqueous layer was re-extracted with DCM (2×150 ml) dried (MgSO4) the resulting residue purified by prep HPLC
