2-{[7-(Benzyloxy)-6-methoxy-4-quinolyl]sulfanyl}-5-nitro-1,3-thiazole (2.0 g), trifluoroacetic acid (20 ml) and thioanisole (2 ml) were stirred together at 65° C. for 90 minutes. The mixture was returned to room temperature, the solvent was distilled off under reduced pressure, 40 ml of methanol was added to the residue, and then sodium bicarnobate water was added until the foaming subsided. The precipitated solid was filtered out to obtain 1.4 g of a yellow powder.
