Cesium carbonate → (2-[(2,3-Difluorobenzyl)thio]-6-{(1R)-1-[(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]ethoxy}pyrimidin-4-yl)methanesulfonamide

Participants

Reaction Steps

The subtitle compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of methane sulfonamide (0.25 g), tris(dibenzylideneacetone)dipalladium (0) (55 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (29 mg), cesium carbonate (0.30 g) and 4-chloro-2-[(2,3-difluorobenzyl)thio]-6-{(1R)-1-[(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]ethoxy}pyrimidine (the product of Example 47, step i) (0.25 g) in dioxane (5 ml). The crude material was purified by column chromatography using EtOAc/isohexane (2:8) as eluent to give the subtitle compound as a yellow oil. Yield: 0.25 g.
