To the solution of methyl 6-quinolineacetate (1.2 g, 6 mmol) in dioxane (30 mL) was added Selenium dioxide (1.65 g, 15 mmol). The mixture was heated to reflux for 3 days, cooled to room temperature, filtered through Celite and concentrated. The residue was purified by chromatography (methylene chloride to 5% ethyl acetate in chloride) to a white solid (0.75 g, 58%). 1H-NMR (CDCl3): δ 9.07-9.06 (1H, q, J=1.7, 2.5 Hz), 8.62-8.61 (1H, d, J=1.7 Hz), 8.32-8.31 (2H, m), 8.22-8.20 (1H, d, J=8.8 Hz), 7.54-7.51 (1H, q, J=8.8 Hz), 4.05 (3H, s).
