Procedure
tert-Butyl 3-[2-methyl-6-(4-oxo-4H-1,3-benzothiazin-2-yl)-4-pyridyl]propanoate (0.96 g, 2.5 mmol) was dissolved in trifluoroacetic acid (8 ml), and the mixture was stirred at 0° C. for 2 hrs. The solvent was evaporated, and the residue was recrystallized from diisopropyl ether-ethanol to give the titled compound (0.74 g, 90%) as white crystals.
