Reaction Steps

tert-Butyl {[6-(4-oxo-4H-1,3-benzothiazin-2-yl)-2-pyridyl]thio}acetate (0.34 g, 1.00 mmol) was dissolved in chloroform (20 ml), and a solution of 3-chloroperbenzoic acid (ca. 77%, 0.23 g, 1.00 mmol) in chloroform (10 ml) was added 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 (0.30 g, 75%) as pale yellow crystals.
