실험 절차

15 Grams of 6-(4-hydroxyimino-1-piperidylcarbonyl)-3,4-dihydrocarbostyril, 11.4 ml of acetic anhydride and 31.8 ml of triethylamine in 300 ml of methylene chloride solution were mixed together and stirred at room temperature overnight. The reaction mixture was poured into ice-water, and extracted with chloroform. The chloroform extract was dried with anhydrous sodium carbonate, then the solvent was removed by evaporation to yield 16.5 g of 6-(4-acetyloxyimino-1-piperidylcarbonyl)-3,4-dihydrocarbostyril.
