Procedure
To a solution of N-[2-[[(2,3-difluorophenyl)methyl]thio]-6-[(1R)-1-[(4R)-2,2-dimethyl-1,3-dioxolan-4-yl]ethoxy]-4-pyrimidinyl]-methanesulfonamide (the product of step i) (0.23 g) in DCM (5 mL) was added iron (III) chloride hexahydrate (0.25 g). The reaction mixture was stirred at ambient temperature for 2 h then saturated aqueous sodium bicarbonate (2 mL) was added. The layers were separated and the aqueous material extracted with DCM (×3) and ethyl acetate (×3). The combined organic extracts were washed with brine, dried (MgSO4), filtered and evaporated. The residual yellow solid was precipitated from 10% DCM in Et2O, filtered and the resulting material washed with minimal Et2O (2×1 mL) to afford the title compound as a white powder. Yield: 24 mg.
