6-Fluoro-4-hydroxyquinoline was reacted with 40% aqueous formaldehyde in aqueous sodium hydroxide solution to give the novel 6-fluoro-4-hydroxy-3-hydroxymethylquinoline m.p. 310°-315°. The product was methylated with dimethyl sulphate to give the novel 6-fluoro-1-methyl-3-hydroxymethyl-4-quinolone, m.p. 209°-212°. Reaction of this product with thionyl chloride, then sodium methanethiolate gave the novel 6-fluoro-1-methyl-3-methylthiomethyl-4-quinolone, m.p. 114°-116° (from industrial methylated spirit).
