Participants

Reaction Steps

3-[4-hydroxy-3-(1,3-thiazolidine-3-carbonyl)-5-trifluoromethylbenzoyl]-1,1-dioxo-2,3-dihydro-1,3-benzothiazole (67 mg) was dissolved in tetrahydrofuran (0.5 mL) and water (0.5 mL), and oxone (45 mg) was added to the solution, and then the mixture was stirred at room temperature for 1 hour. To the reaction solution, 1N hydrochloric acid was added, and then the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure and the obtained residue was crystallized from n-hexane-chloroform to obtain the title compound (46 mg) as a colorless crystal.
