実験手順

To a solution of 4-chloro-1-(4-methoxybutyl)-2-phenyl-1H-imidazole-5-carbaldehyde (790 mg) in tert-butanol (15 ml) and 2-methyl-2-butene (1.5 ml) was added aqueous solution (4 ml) of sodium chlorite (300 mg) and sodium dihydrogen phosphate (400 mg), and the mixture was stirred at room temperature for 12 hr. 1M Hydrochloric acid was added, and the mixture was adjusted to pH 3, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object product (730 mg).
