Procedure

The title compound was prepared according to the procedure outlined in example 1 step (iv) using a mixture of azetidine-1-sulfonamide (150 mg), tris(dibenzylideneacetone)dipalladium (0) (25 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (25 mg), cesium carbonate (244 mg) and (2R,3R)-3-({6-chloro-2-[(2,3-difluorobenzyl)thio]pyrimidin-4-yl}oxy)butan-2-ol (200 mg) in anhydrous dioxane (10 ml). Purification was by reverse phase HPLC eluting with acetonitrile/aq. 0.1% ammonium acetate mixtures to give title compound as a white solid. Yield: 79 mg
