Reaction Steps
In a similar fashion using route 18 general procedure 27, 8-aminoquinoline (1.6 g, 11.1 mmol), 5-fluoro-2-nitro-benzenesulfonyl chloride (Intermediate 450) (3.4 g, 14.4 mmol), pyridine (4.48 ml, 55.5 mmol), DMAP (cat.) and DCM (6 ml) gave the title compound (0.95 g, 25%) after purification by column chromatography with n-hexane/DCM (50:50) as the eluent. The structure was confirmed by 1H NMR.
