Reaction Steps

To a solution of N-[2-[[(2,3-difluorophenyl)methyl]thio]-6-[(2S)-1,4-dioxaspiro[4.5]dec-2-ylmethoxy]-4-pyrimidinyl]-1-azetidinesulfonamide (the product of step ii) (0.34 g) in methanol (5 mL)/H2O (0.1 mL) was added pyridinium p-toluenesulfonate (78 mg) and the mixture was stirred at reflux for 2 h and then ambient temperature for 20 h. The reaction mixture was evaporated, suspended in H2O and extracted with EtOAc (×2). The combined organic layers were dried (MgSO4), filtered and evaporated. The residue was purified by column chromatography on silica gel using DCM/MeOH (98:2) as eluent to give the title compound as a white solid. Yield: 0.15 g
