To a solution of 32 (50 mg, 0.094 mmol) in THF (1 mL) was added azetidine (20 μL). The reaction mixture was heated at 70° C. for 30 min. A saturated solution of NH4Cl (3 mL) was added, and the layers were separated. The aqueous layer was extracted with EtOAc. The combined organic layer were dried, filtered, and concentrated in vacuo. The crude material was purified by column chromatography (EtOAc/hexanes) to give 38 mg of 33. LCMS-ESI+: calc'd for C20H25F3N2O6S2: 511.1 (M+H+); Found: 511.0 (M+H+).
