Participants

Reaction Steps

The title compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 2-amino-4-methyl-1,3-thiazole-5-sulfonamide (0.23 g), tris(dibenzylideneacetone)dipalladium (0) (73 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (38 mg), cesium carbonate (0.39 g) and 4-Chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine (the product of Example 35, step i) (0.24 g) in dioxane (6 ml). The crude material was purified by column chromatography using EtOAc/isohexane (2:8 to 4.5:5.5 gradient) as eluent and trituration with Et2O to give the title compound as a beige solid. Yield: 0.15 g.
