Procedure

A mixture of tert-butyl (3S)-4-(aminosulfonyl)-3-methylpiperazine-1-carboxylate (0.372 g), tris(dibenzylideneacetone)dipalladium (0) (50 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (50 mg), cesium carbonate (0.286 g) and 4-Chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine ((the product from example 35 step i), 0.373 g) in dioxane (20 ml) was heated at reflux in a microwave at 100° C., 300 W, open vessel with cooling for 60 min. The reaction mixture was then reduced in vacuo and the residue separated between DCM (150 ml) and H2O (100 ml). The organics were separated and the aqueous layer was re-extracted with DCM (3×150 ml). Organics were combined, dried (MgSO4) and reduced in vacuo to give the subtitle compound as a yellow solid. Yield: 0.65 g
