실험 절차

The sodium salt of 5-(3-acetyl-2,4,6-trimethylphenyl)-2-[1-(ethoxyimino)butyl]-3-hydroxy-cyclohex-2-en-1-one (0.10 g; 0.26 mmole) was dissolved in acetone and then 4-toluenesulfonyl chloride (0.05 g; 0.26 mmole) was added. The mixture was stirred for 15 minutes and then the solvent was removed by evaporation under reduced pressure using a rotary evaporator. The product was purified by column chromatography over silica gel (eluant dichloromethane) to give 5-(3-acetyl-2,4,6-trimethylphenyl)-2-[1-(ethoxyimino)butyl]-3-(4-toluenesulfonyl)oxy-cyclohex-2-en-1-one (0.13 g; 95.6%) as a yellow oil.
