Procedure

A mixture of 2-n-butyl-1-(2-chlorophenyl)methyl-5-(a-hydroxy)ethyl-1H-imidazole (1.07 g, 3.65 mmol), activated maganese dioxide (6 g) and toluene (75 mL) was heated at 90° to 100° C. under a slight vacuum with a Dean-Stark water separator for 17 hours. The inorganics were filtered, the concentrated filtrate was applied to a flash silica gel column, and the product was eluted with 3:7 hexane/ethyl acetate to give 0.628 g (59%) of [2-n-butyl-1-{(2-chlorophenyl)methyl}-1H-imidazol-5-yl]methyl ketone.
