Procedure

This was then treated with sulphuric acid as described for 2-methyl-6-fluoro-9-thioxanthone. The resulting substance consisted mainly of 2-trifluoro-6-methyl-9-thioxanthone with some 2-trifluoromethyl-8-methyl-9-thioxanthone. When boiling this mixture with acetone the more soluble 8-methyl-compound will go into solution. The remaining 2-trifluoromethyl-6-methyl-9-thioxanthone was obtained as a yellow crystalline substance, which melts at 174-178 degrees Centigrade.--Yield: 80 grams.
