A mixture of morpholine-4-sulfonamide (prepared according to patent WO 2004/011443, 0.399 g), tris(dibenzylideneacetone)dipalladium (0) (50 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-isopropyl-1,1′-biphenyl (XPHOS) (50 mg), cesium carbonate (0.585 g) and 2-({6-chloro-2-[(2,3-difluorobenzyl)thio]pyrimidin-4-yl}oxy)ethanol (the product from example 112 step ii), 0.400 g) in dioxane (20 ml) was heated at reflux in a microwave at 100° C., 300 W, open vessel with cooling for 30 mins. The reaction mixture was then reduced in vacuo and the residue separated between DCM (150 ml) and H2O (100 ml). The organics were separated and the aqueous layer was re-extracted with DCM (2×150 ml). Organics were combined, dried (MgSO4) and reduced in vacuo and the resulting residue purified by prep HPLC to give the title compound as a white solid. Yield: 0.15 g
