実験手順

One gram of 3,5-di-t-butyl-4-hydroxybenzophenone was added to 2 ml of 1,1-dimethylhydrazine, and the mixture was heated at 70° to 75° C. for 8 hours in the presence of 20 mg of p-toluenesulfonic acid in autoclave. After cooling, the reaction mixture was poured into water and extracted with diethyl ether. The ethereal layer was washed with water and dried. The ether was distilled, and the residue was chromatographed on a silica gel column, and recrystallized from diethyl ether to give 3,5-di-t-butyl-4-hydroxybenzophenone dimethylhydrazone as pale yellow needles.
