Versuchsvorschrift

A mixture of 5'-fluoro-N-methyl-2'-methylsulphinylacetylformanilide (1.99 g), prepared in a similar manner to that described in Example 8, and aqueous sodium hydroxide solution (1M; 50 ml) was stirred for 2 hours at ambient temperature and then filtered. The solid was washed with water (2×10 ml) and then toluene (2×10 ml). The solid was dried at 50° in vacuo to give 7-fluoro-1-methyl-3-methylsulphinyl-4-quinolone, m.p.228.5°-230° (1.55 g).
