実験手順
tert-Butyl 3-[2-(methylsulfinyl)-6-(4-oxo-4H-1,3-benzothiazin-2-yl)-4-pyridyl]propanoate (0.12 g, 0.28 mmol) was dissolved in trifluoroacetic acid (5 ml), and the mixture was stirred at room temperature for 0.5 hr. Diisopropyl ether was combined with the reaction mixture to give precipitates, which were recrystallized from ethanol to give the titled compound (0.095 g, 91%) as white crystals.
