Procedure

A mixture of (trans)-tert-butyl 3-fluoro-4-(methylsulfonyloxy)piperidine-1-carboxylate (24 mg, 0.0807 mmol), 2-(6-fluoro-[1,2,4]triazolo[4,3-a]pyridin-3-yl)quinolin-8-ol (23.8 mg, 0.0850 mmol) and Cs2CO3 (55.4 mg, 0.170 mmol) in DMA (425 μl, 0.0850 mmol) was heated to 90° C. for 16 hours. The mixture was transferred to a separatory funnel and diluted with EtOAc and water. The mixture was then extracted with EtOAc, and the combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated to a residue under reduced pressure to give the product without further purification (33 mg, 81% yield). MS APCI (+) m/z 481.9 (M+1) detected.
