Reaktionsschritte

To a 100 mL volume three-necked flask, ethyl 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetate ((9-a) (10.0 g)) and toluene (35 ml) were added. Hydrazine hydrate (2.13 ml) was added dropwise thereto at 60° C. and the obtained mixture was stirred at 70° C. for 7 hours. The reaction mixture was cooled to room temperature, water was added thereto and the organic layer was removed. The aqueous layer was extracted with toluene. The organic layers were combined and concentrated under reduced pressure to give 9.40 g of 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetohydrazide ((12-1)-(11)-39).
