Cesium carbonate → N-{2-[(2,3-Difluorobenzyl)thio]-6-methoxypyrimidin-4-yl}-4-pyrimidin-2-ylpiperazine-1-sulfonamide

Participants

Reaction Steps

The title compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 4-pyrimidin-2-ylpiperazine-1-sulfonamide (0.24 g), tris(dibenzylideneacetone)dipalladium (0) (60 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (31 mg), cesium carbonate (0.32 g) and 4-Chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine (the product of Example 35, step i) (0.20 g) in dioxane (6 ml). The crude material was purified by column chromatography using EtOAc/isohexane (2:8 to 1:1 gradient) as eluent to give the title compound as a pale yellow foam. Yield: 0.19 g.
