2-[6-(3-Phenylpropyl)thio-2-pyridyl]-4H-1,3-benzothiazine-4-one (0.20 g, 0.50 mmol) was dissolved in chloroform (30 ml), and a solution of 3-chloroperbenzoic acid (ca. 70%, 0.11 g, 0.50 mmol) in chloroform (10 ml) was added dropwise thereto. The reaction mixture was stirred at room temperature for 1 hr. The solvent was evaporated, and the residue was recrystallized from ethanol to give the titled compound (0.063 g, 31%) as pale yellow crystals.
