실험 절차

tert-Butyl 3-[6-(7-fluoro-4-oxo-4H-1,3-benzothiazin-2-yl)-2-pyridyl]propanoate (0.50 g, 1.3 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 diethyl ether to give the titled compound (0.43 g, 99%) as white crystals.
