Reaction Steps

Pyridine (0.5 ml) and a methylenechloride (0.5 ml) solution containing 6-ethyl-3-pyridinesulfonyl chloride (30 ml) were added to 3-amino-8-bromoquinoline (18 mg, Production Example 5b) at 0° C. After stirring at room temperature for 30 minutes, water was added thereto and the mixture was extracted with ethyl acetate. The extract was purified by preparative TLC (hexane-ethyl acetate=1:1), to give the title compound (20 mg).
