Participants

Reaction Steps

A mixture of 3-hydroxy-3-methylazetidine-1-sulfonamide (0.25 g) (prepared according to patent WO 2004/011443), tris(dibenzylideneacetone)-dipalladium (0) (13 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (10 mg), cesium carbonate (0.68 g) was treated with a solution of 4-Chloro-2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidine (the product of example 35 step i) (0.4 g) in dioxane (10 ml) and the whole then heated at reflux for 30 min. H2O (10 ml) was added followed by 1N hydrochloric acid solution (5 ml) and the resulting mixture extracted with EtOAc. The combined organic extracts were washed with saturated aqueous sodium chloride, dried (MgSO4), filtered and evaporated. The residue was purified by column chromatography on silica gel using EtOAc/DCM (1:4) as eluent to give the subtitle compound as a white solid.
