Procedure
tert-Butyl 2-[2-(4-oxo-4H-1,3-benzothiazin-2-yl)-4-pyridyl]-1-pyrrolidinecarboxylate (0.35 g, 0.85 mmol) was dissolved in trifluoroacetic acid (5 ml), and the mixture was stirred at room temperature for 3 hrs. The solvent was evaporated, and the residue was recrystallized from diisopropyl ether-methanol to give the titled compound (0.31 g, 85%) as white crystals.
