Procedure

A mixture of 5'-fluoro-N-methyl-2'-methylsulphonylacetylformanilide (1.50 g), prepared in a similar manner to that described in Example 11, and aqueous sodium hydroxide solution (1M; 40 ml) was stirred for 2 hours. The mixture was filtered, the solid washed with water (2×10 ml) and then dried in vacuo to give 7-fluoro-1-methyl-3-methylsulphonyl-4-quinolone, m.p.234°-235° (1.19 g).
