Reaction Steps

A mixture of 5'-fluoro-N-methyl-2'-methylsulphonylacetylformanilide (0.20 g), prepared in a similar manner to that described in Example 11, and triethylamine (20 ml) was stirred at ambient temperature for 2.5 hours. Hexane (30 ml) was added to the mixture. The solid product collected by filtration of the mixture was washed with hexane (2×5 ml) and dried at 50° in vacuo to give 7-fluoro-1-methyl-3-methylsulphonyl-4-quinolone, m.p. 233°-234.5° (0.16 g).
