Procedure

tert-Butyl 3-[6-(4-oxo-4H-1,3-benzothiazin-2-yl)-3-pyridyl]propanoate (0.21 g, 0.56 mmol) was dissolved in trifluoroacetic acid (5 ml), and the mixture was stirred at room temperature for 0.5 hr. Diisopropyl ether was added to the reaction mixture to give crystals, which were recrystallized from ethanol to give the titled compound (0.12 g, 68%) as white crystals.
