Versuchsvorschrift
To a 50 mL volume three-necked flask, 1.0 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-2-(phenylmethylidene)hydrazine ((40-a)-(14)-6), 3.5 ml of toluene and 629 mg of potassium carbonate were added and then, 9.1 mg of N,N-dimethylhydrazine solved in 2.3 ml of toluene and 577 mg of dimethyl sulfate were added thereto at 5° C. The mixture was stirred at 5° C. for 24 hours, 3 g of water was added thereto and the organic layer was removed. The aqueous layer was extracted with 3.5 ml of toluene two times. The organic layers were combined and concentrated under reduced pressure to give 1.037 g of a mixture (19:1 (GC area %)) of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-(phenylmethylidene)hydrazine ((40-b)-(15)-5) and methyl 2-(2,6-diethyl-4-methylphenyl)-2-oxo-N-(phenylmethylidene)ethanehydrazonate (x-1).
