70 g (1.26 mol) of hydrazine hydrate were added dropwise at 10 to 30° C. to a solution of 100 g (0.62 mol) of ethyl isobutyrylacetate in 60 ml of ethanol. After the exothermic reaction had subsided, the mixture was stirred at 20 to 25° C. for a further 14 hours approximately and was then cooled to approximately −10° C. 52 g of the title compound were isolated by filtration.
