Procedure

60% Sodium hydride (0.42 g) was added to a solution of N-[2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidin-4-yl]azetidine-1-sulfonamide (the product of Example 35) (3.82 g) in anhydrous DMF (38 ml) stirred at 0° C. under nitrogen. The reaction mixture was stirred for a further 15 min when 4-methoxybenzylchloride (2.98 g) was added dropwise over one min followed by potassium iodide (1.66 g). After stirring at room temperature for 18 h. the reaction mixture was partitioned between EtOAc and H2O. The aqueous layer was separated and further extracted with EtOAc (2×). The combined organic extracts were washed with H2O, dried (MgSO4), filtered and the solvent evaporated under reduced pressure. The residue was purified by flash column chromatography on silica gel using EtOAc/iso-hexane (2:8) as eluent. The product was further purified by flash column chromatography on silica gel using DCM/isohexane (6:4) as eluent to give the subtitle product as a white solid. Yield: 2.4 g.
