Reaction Steps

6-Bromoimidazo[1,2-a]pyridin-8-ol hydrochloride (40 mg, 0.16 mmol) and Cs2CO3 (104 mg, 0.32 mmol) in acetone (0.64 mL) and DMF (0.2 mL) was added ethyl bromide (12 μL). The reaction was stirred for 48 h then the volatile solvents were removed and the residue then added water (0.8 mL). The resulting solids were stirred, filtered, and rinsed with water. The water filtrate was extracted with EtOAc and then combined with the solid crude products. The residue was purified via column chromatography (25% then 50% EtOAc/heptane) to afford the product (19 mg, 50% yield).
