2-(7-methyl-[1,2,4]triazolo[4,3-a]pyridin-3-yl)quinolin-8-ol (300 mg, 1.09 mmol) was suspended in CH3CN (5 mL) at ambient temperature, and trans-tert-butyl 4-fluoro-5-(4-nitrophenylsulfonyloxy)azepane-1-carboxylate (454 mg, 1.09 mmol) and 2-tert-butyl-1,1,3,3-tetramethylguanidine (263 μL, 1.30 mmol) were added. The dark solution was stirred at 40° C. overnight, then concentrated to a grey solid which was slurried in water for 10 minutes. The solid was filtered, washed and dried in vacuo to provide the desired product. MS ESI (+) m/z 492.3 (M+1) detected.
