Versuchsvorschrift

3-Chloromethyl-1-methyl-7-trifluoromethyl-4-quinolone hydrochloride (4.7 g.) was added to a stirred solution of sodium methanethiolate in methanol (16 ml. containing 0.039 mole NaSMe) at 0° during 5 minutes. The resulting mixture was allowed to warm to room temperature then poured into water (100 ml.). The resulting precipitate was collected, dried and crystallised from dichloromethane:petroleum ether (b.p. 60°-80°) to give the novel 1-methyl-3-methylthiomethyl-7-trifluoromethyl-4-quinolone, m.p. 182°-184°.
