Reaction Steps

The subtitle compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 4-(aminosulfonyl)-1-piperazinecarboxylic acid-1,1-dimethylethyl ester (the product from example 15, step i), 0.40 g), tris(dibenzylideneacetone)dipalladium (0) (91 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (48 mg), cesium carbonate (0.49 g) and 4-chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-(2,2,2-trifluoroethoxy)-pyrimidine (the product from example 16, step i) (0.37 g) in dioxane (6 mL). Purification was by column chromatography on silica gel using EtOAc/isohexane (1:9 to 2:8 gradient) as eluent to give the subtitle compound as a yellow solid. Yield: 0.22 g
