実験手順
2-[6-[(Ethylthio)methyl]-2-pyridyl]-4H-1,3-benzothiazine-4-one (0.10 g, 0.32 mmol) was dissolved in chloroform (50 ml), and a solution of 3-chloroperbenzoic acid (ca. 77%, 0.071 g, 0.32 mmol) in chloroform (10 ml) was added dropwise thereto. The mixture was stirred at room temperature for 1 hr. The solvent was evaporated, and the residue was recrystallized from n-hexane-ethyl acetate to give the titled compound (0.095 g, 91%) as pale yellow crystals.
