Cesium carbonate → N-[6-(difluoromethoxy)-2-[[(2,3-difluorophenyl)methyl]thio]-4-pyrimidinyl]-1-methyl-1H-imidazole-4-sulfonamide

Participants

Reaction Steps

The title compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 1-methyl-1H-imidazole-4-sulfonamide (0.25 g), tris(dibenzylideneacetone)dipalladium (0) (0.10 g), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (60 mg), cesium carbonate (0.26 g), 4-chloro-6-(difluoromethoxy)-2-[[(2,3-difluorophenyl)methyl]thio]-pyrimidine (product of example 12, step ii) (0.18 g) and anhydrous dioxane (5 ml). Purification was by tituration with methanol/DCM. The resulting white solid was diluted with H2O and extracted with EtOAc. The organic layer was washed with H2O (×2) then brine and dried (MgSO4), filtered and evaporated. The resulting oil was triturated with methanol/DCM to give the title compound as a white solid. Yield: 15 mg
