Reaction Steps

A mixture of azetidine-1-sulfonamide (prepared according to patent WO 2004/011443, 0.32 g), tris(dibenzylideneacetone)-dipalladium (0) (33 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (17 mg), cesium carbonate (0.58 g) and 4-chloro-2-[(2,3-difluorobenzyl)thio]-6-(methylthio)pyrimidine (the product of example 57, step i) (0.38 g) in dioxane (10 mL) was heated at 100° C. for 18 h. The mixture was cooled and saturated ammonium chloride was added 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 reverse phase HPLC eluting with acetonitrile/aq. 0.1% ammonium acetate mixtures to give the title compound as a white solid. Yield: 50 mg.
