Reaction Steps

To a suspension of N-[2-[[(2,3-difluorophenyl)methyl]thio]-6-[1-[(4R)-2,2-dimethyl-1,3-dioxolan-4-yl]-1-methylethoxy]-4-pyrimidinyl]-1-azetidinesulfonamide (the product from step iii) 0.34 g) in DCM (9 mL) was added iron (III) chloride hexahydrate (0.61 g) and the mixture was stirred at ambient temperature for 35 min. The reaction mixture was diluted with sat. sodium hydrogencarbonate solution and extracted with DCM (×3). The combined organic layers were dried (MgSO4), filtered and evaporated. The residue was purified by column chromatography on silica gel using MeOH/DCM (99:1 to 98:2 gradient) as eluent to give the title compound as a white foam. Yield: 0.20 g
