실험 절차
A solution of 5'-fluoro-N-methyl-2'-methylsulphonylacetylformanilide (0.20 g), prepared in a similar manner to that described in Example 11, in 2-methoxyethanol (25 ml) was heated to reflux. Heating under reflux at 127° was continued for 2 hours. The mixture was allowed to cool to ambient temperature and then evaporated in vacuo to give 7-fluoro-1-methyl-3-methylsulphonyl-4-quinolone, m.p. 233.5°-235° (0.19 g).
