Procedure
To a solution of 5-cyano-N-{2-[(2,3-difluorobenzyl)thio]-6-[(1R)-1-methyl-2-(triphenylmethyloxy)ethoxy]pyrimidin-4-yl}furan-2-sulfonamide (the product of step ii) (0.15 g) in methanol (5 mL) was added para-toluenesulfonic acid hydrate (39 mg) and anisole (0.23 mL). After stirring at room temperature for 5 h, H2O (5 mL) was added and the mixture extracted with EtOAc (3×10 mL). The combined organic layers were washed with brine (10 mL), dried (MgSO4), filtered and evaporated to dryness in vacuo. The resulting crude solid was purified by reverse phase HPLC (75% to 5% gradient of 0.1% aqueous ammonium acetate in acetonitrile as eluent) to give the title compound as a white solid. Yield: 20 mg.
