Versuchsvorschrift
A mixture of 1,5-dimethyl-4-hydroxymethyl-2-(4-trifluoromethylphenyl)imidazole (0.5 g) and manganese dioxide (2 g) in 20 ml of chloroform was refluxed for 24 hours. A further 2 g of manganese dioxide was added, and the mixture refluxed for a further 3 hours. The mixture was cooled, the solid material filtered off, and washed with methylene chloride. The solvent was removed from the filtrate under reduced pressure, to yield 0.5 g of 1,5-dimethyl-4-formyl-2-(4-trifluoromethylphenyl)imidazole, m.p. 144° C.
