Mitsunobu coupling between isopropyl 3-(hydroxymethyl)pyridine-2-carboxylate (I) and N-tosyl glycine methyl ester (II) affords amino diester (III). Diester (III) is subsequently converted to the naphthyridine (IV) under Dieckmann cyclization conditions. Bromination of naphthyridine (IV) by means of N-bromosuccinimide provides (V). The methyl ester group of (V) is then displaced with 4-fluorobenzylamine (VI) to furnish amide (VII). Finally, copper-catalyzed displacement of the bromide (VII) with butanesultam (VIII) provides the title compound.
