실험 절차

A mixture of 15.6 (0.06 mole) of 6,7-methylenedioxy-4(1H)-quinolone-3-carboxylic acid, ethyl ester (J. Med. Chem. 11, 160 (1968)) and 1.5 g. (0.062 mole) of sodium hydride powder in 250 ml. of dimethyl formamide was heated with stirring for 0.5 hour at 80°-90° C. 2,2,2-Trifluoroethyl trichloromethanesulfonate (17.5 g. 0.62 mole) was then added dropwise. The temperature is maintained at 80°-90° for an additional 2 hours. The cooled mixture was poured into ice water and the solid product was isolated by filtration. It was recrystallized from ethanol. This product was identical to that obtained from Example 4.
