실험 절차
tert-Butyl 2-[2-(7-chloro-4-oxo-4H-1,3-benzothiazin-2-yl)-4-pyridyl]ethylcarbamate (0.36 g, 0.86 mmol) was dissolved in trifluoroacetic acid (10 ml), and the mixture was stirred at room temperature for 3 hrs. The solvent was evaporated, and the residue was recrystallized from methanol-diisopropyl ether to give the titled compound (0.33 g, 89%) as white crystals.
