Participants

Reaction Steps

After tert-butyl 3-[3-(4-oxo-4H-1,3-benzothiazin-2-yl)phenyl]propionate (0.19 g, 0.52 mmol) was dissolved in trifluoroacetic acid (1.0 ml), the mixture was stirred at room temperature for 2 hours. Isopropyl ether was added to the reaction solution and the precipitated crystals were taken by filtration. The precipitates were recrystallized from ethanol-isopropyl ether to give the title compound (0.056 g, 35%) as crystals.
