Versuchsvorschrift

To a 100 mL volume three-necked flask, 5.0 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-2-(phenylmethylidene)hydrazine ((40-a)-(14)-6), 31 ml of methyl isobutyl ketone, 6.43 g of potassium carbonate and 1.75 ml of dimethyl sulfate were added and the mixture was stirred at room temperature for 7.5 hours. Water was added to the reaction mixture, the organic layer was removed and then the aqueous layer was extracted with 31 ml of methyl isobutyl ketone. The organic layers were combined, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give 0.324 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-(phenylmethylidene)hydrazine ((40-b)-(15)-5)) and 0.324 g of methyl 2-(2,6-diethyl-4-methylphenyl)-2-oxo-N-(phenylmethylidene)ethanehydrazonate (X-1).
