Participants

Reaction Steps

Oxone® (614.8 mg, 1 mmol) was dissolved in water (10 ml) and the pH was adjusted to pH7 with NaHCO3. To the solution was then added tetrabutylammonium hydrogen sulfate (20 mg). The resulting solution was added at room temperature to a solution of 5,6-dichloro-1-methylsulfanylmethyl-2-(2,2,2-trifluoro-ethyl)-1H-benzoimidazole, prepared as in Example 47, (109.6 mg, 0.33 mmol) in EtOAc (4 mL). The Oxone® solution (608.87 mg) was added until the reaction completed. The resulting mixture was washed with 1 N NaOH, then extracted with EtOAc. The organic layer was washed with 15% NaCl, dried over MgSO4 and the solvent was distilled under reduced pressure to yield the title compound as a yellow solid.
