Versuchsvorschrift

White crystals (197 mg, 0.556 mmol) were obtained in the same manner as in Example 1, except using 100 mg (0.56 mmol) of 3-amino-8-bromoquinoline (Preparation Example 5) and 142 mg (0.67 mmol) of 2-chloro-5-pyridinesulfonyl chloride. To the crystals (60 mg, 0.17 mmol) were added dimethylformamide (1 ml), pyridine (1 ml) and sodium thiomethoxide (111 mg, 1.6 mmol), followed by stirring at room temperature for 3 hours. TO the reaction mixture was added brine, followed by extracting with ethyl acetate. The organic layer was dried over magnesium sulfate and concentrated. The resulting residue was purified by silica gel chromatography, to give 62 mg of the title compound.
