実験手順
In acetic acid was dissolved 2-benzyloxy-N-[1-(3,5-dichlorophenylthio)-3-methyl-2-oxobutyl]-N-methylacetamide (20), followed by addition of ammonium acetate, and the mixture was refluxed under heating. After 1 hour, the reaction mixture was concentrated under reduced pressure, neutralized with sodium hydroxide, and then, extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated to give 2-benzyloxymethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1H-methylimidazole (17a).
