Versuchsvorschrift

To the crude alcohol from above was added MnO2 and CHCl3 (20 mL). The mixture was stirred overnight at 25° C. and filtered, and the organic solvent was evaporated. The crude residue was purified by flash chromatography on silica gel eluting with 1:6 ethyl acetate-hexane to give 0.3 g of 3,5-di-t-butylbenzaldehyde as a white solid.
