Versuchsvorschrift
To a solution of 10 grams of 4,4-dimethyl-2-(3-chloro-4-fluorophenyl)semicarbazide in 200 milliliters of benzene was added 8.1 grams of m-trifluoromethylacetophenone. This mixture was stirred and heated at reflux for 18 hours. The solvent was removed and the residue purified by silica chromatography to give 13 grams (75.1 yield) of 2-trifluoromethylacetophenone, 4,4-dimethyl-2-(3-chloro-4-fluorophenyl) semicarbazone as an amber syrup.
