Procedure

cis-tert-butyl 4-fluoro-5-(4-nitrophenylsulfonyloxy)azepane-1-carboxylate (0.484 g, 1.16 mmol) and 2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoroquinolin-8-ol (0.300 g, 1.07 mmol) were slurried in CH3CN (5.0 mL). To this mixture was added 2-tert-butyl-1,1,3,3-tetramethylguanidine (0.259 mL, 1.28 mmol) dropwise. The dark solution was warmed to 40° C. and stirred overnight. The mixture was cooled to ambient temperature and diluted with water (10 mL) and stirred for 15 minutes, then filtered. The solid was washed with water and hexanes and dried in vacuo. The product was purified via column chromatography (10 to 50% Acetone/CH2Cl2) to provide the product as off-white solid. MS ESI (+) m/z 496.0 (M+1) detected.
