A mixture of piperidine-4-sulfonamide (0.33 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, 4-Chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine (the product from example 35 step i), 0.4 g) in dioxane (20 ml) was heated at reflux in a microwave at 100° C., 300 W, open vessel with cooling for 2 h. The reaction mixture was then reduced in vacuo and the residue partitioned between DCM (100 ml) and H2O (100 ml). The organics were separated and the aqueous layer was re-extracted with DCM (2×100 ml). Organics were combined, dried (MgSO4) and reduced in vacuo and the resulting yellow residue was purified prep HPLC to give the title compound as a white solid. Yield 13 mg
