To a solution of 2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)quinolin-8-ol (100 mg, 0.38 mmol), Example 1, Step D, in anhydrous DMA (2 mL) was added cesium carbonate (373 mg, 1.14 mmol) followed by neopentyl iodide (101 μL, 0.76 mmol). The heterogeneous mixture was stirred at ambient temperature for 2 hours then at 100° C. for 16 hours. The cooled mixture was treated with water (30 mL) and extracted with EtOAc (3×20 mL). The combined organic phases were washed with water and brine, dried over Na2SO4 and concentrated to afford a cream-colored solid. This was triturated with ether and the resulting solid collected by filtration and dried in vacuo to provide desired product (62 mg, 49%) as a white powder. MS ESI (+) m/z 333.3 (M+1) detected.
