実験手順
To a hot solution of 10 g 4,4'-dimethylbenzil in 20 ml of ethanol is added 2.1 g of hydrazine hydrate. After a few minutes at reflux, a solid begins to crystallize. Heating is continued for 10 min. and the solution cooled slowly to 0° C. The solid is filtered off and washed with cold ethanol. The product is recrystallized from ethanol. Yield 7.1 g. M.P. 137°-140°.
