Procedure
A mixture of tert-butyl 2-[[4-oxo-2-(2-pyridyl)-4H-1,3-benzothiazin-6-yl]oxy]acetate (0.30 g, 0.81 mmol) and trifluoroacetic acid (10 ml) was stirred at room temperature for 3 hrs. The reaction mixture was concentrated under reduced pressure and recrystallized from methanol-diisopropyl ether to give the titled compound (0.17 g, 67%).
