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

Participants

Reaction Steps

The subtitle compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of 4-morpholine sulfonamide (prepared according to patent WO 2004/011443) (0.15 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 (1:9 to 2.5:7.5 gradient) as eluent to give the subtitle compound as an off-white foam. Yield: 0.20 g.
