Procedure

Manganese dioxide (20 g, 0.23 mol) was added to a solution of [5-(1,1-dimethyl-allyl)-3H-imidazol-4-yl]-methanol (2.56 g, 0.02 mol) in acetone (300 ml) and the resulting mixture was stirred at room temperature for 5 h. The mixture was filtered through filter paper and the residue was washed with acetone. The filtrate and washings were combined and evaporated to afford 5-(1,1-dimethyl-allyl)-3H-imidazole-4-carbaldehyde (1.82 g, 51%). (Hayashi et al., J. Org. Chem., 65:8402-8405 (2000)).
