実験手順

A solution of 3-picoline (40 mg) and 2-[1-ethoxyimino)butyl]-5-(4,6-dimethoxy-2-methylthio-5-pyrimidyl)cyclohex-2-en-1-one (2) (80 mg) in dichloromethane (10 ml) was treated with trimethylacetyl chloride with stirring at room temperature. After 2 hours the solution was washed with dilute hydrochloric acid (1M, 20 ml), separated, dried over anhydrous magnesium sulphate and evaporated under reduced pressure to give 3-trimethylacetyloxy-2-[1-(ethoxyimino)butyl]-5-(4,6-dimethoxy-2-methylthio-5-pyrimidyl)cyclohex-2-en-1-one (7) as a pale brown oil (100 mg) which was characterized by nuclear magnetic resonance spectroscopy.
