yield of 85% and an overall yield of 2−3%. Key features of this sequence include the coupling of the enol triflate 11 and the arylboronic acid 10 (90%), the thermal deprotection/internal amidation of the coupling product 18 (84%), the use of 2-chloropyridine as an economical alternative to 2,6-di-tert-butylpyridine to promote the reaction of the quinolone 9 and triflicanhydride (85%), the highly stereoselective
