Procedure
(4,5-Dimethylfuran-2-yl)-(3-methylpyridin-2-yl)-methanol (1.17 g) was dissolved in chloroform (30 ml) to prepare a solution. Manganese dioxide (4.69 g) was added to the solution, and the mixture was stirred at room temperature overnight. The reaction solution was filtered through Celite, and the solvent was removed from the filtrate by distillation under the reduced pressure to give (4,5-dimethylfuran-2-yl)-(3-methylpyridin-2-yl)-methanone (940 mg, yield 81%).
