실험 절차

In THF (20 ml) was dissolved (2,4-dimethyl-1,3-thiazol-5-yl)methanol (1.0 g). To the solution was added active manganese dioxide (6.0 g), and the mixture was stirred at room temperature for 3 hours. To the mixture was added active manganese dioxide (3.0 g), and the mixture was stirred at room temperature for 1 hour. The mixture was filtered with Celite and washed with methanol. The solvent was removed under reduced pressure, and the resulting residue was purified with silica gel column chromatography (hexane/ethyl acetate/methanol=10/10/1) to give 2,4-dimethyl-1,3-thiazole-5-carbaldehyde (0.32 g).
