Reaction Steps

A mixture of 4,6-dichloro-2-[(2,3-difluorobenzyl)thio]pyrimidine (product of example 1 step ii) (0.5 g), tris(dibenzylideneacetone)dipalladium(0) (45 mg), 2,2-dimethyl-4-vinyl-1,3-dioxolane (630 mg), tri-n-butylamine (610 mg) and tetra-n-butylammonium chloride (460 mg) in anhydrous N,N-dimethylformamide (6.5 ml) were heated at 90° C. for 3 h. then stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The organic phase was washed with water and brine, dried (MgSO4) and the solvent evaporated under reduced pressure. The residue was purified by flash silica-gel chromatography eluting with 10% diethyl ether in iso-hexane to give the sub-title compound as a yellow viscous oil. Yield: 98 mg.
