Participants

Reaction Steps

The subtitle compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 4-Chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine (the product of example 35 step i) (0.16 g), 3-(tert-butyl-diphenyl-silanyloxy)-azetidine-1-sulfonamide (the product from step i) (0.17 g), tris(dibenzylideneacetone)dipalladium (0) (33 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (24 mg), cesium carbonate (0.16 g) and dioxane (8 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 oil. Yield: 0.12 g
