실험 절차

A solution of 2-n-butyl-1-(2-chlorophenyl)methyl-5-hydroxymethyl-1H-imidazole (5.4 g, 0.0194 mol) in methylene chloride (25 mL) was added to a suspension of activated maganese dioxide (27 g) in methylene chloride (325 mL). The suspension was stirred at room temperature for 17 hours. The solids were filtered, and the filtrate concentrated and flash chromatographed over silica gel with 6:4 hexane/ethyl acetate to afford 4.16 g (78%) of 2-n-butyl-1-(2-chlorophenyl)methyl-1H-imidazol-5-carboxaldehyde as an oil.
