실험 절차

tert-Butyl 3-[6-(7-chloro-4-oxo-4H-1,3-benzothiazin-2-yl)-2-pyridyl]propanoate (0.60 g, 1.5 mmol) was dissolved in trifluoroacetic acid (5 ml), and the mixture was stirred at 0° C. for 2 hrs. The solvent was evaporated and the residue was crystallized from diisopropyl ether to give the titled compound (0.49 g, 96%) as white crystals.
