Procedure

28.6 parts by weight of 2-butyryl-5-(4-ethylphenyl)-cyclohexane-1,3-dione and 6.1 parts by weight of ethoxyamine are stirred in 150 parts by volume of ethanol at room temperature for 8 hours. The mixture is concentrated under reduced pressure, the residue is taken up in 200 parts by volume of methylene chloride and the solution is washed with 5% strength aqueous hydrochloric acid and water dried over sodium sulfate and concentrated under reduced pressure. 2-(Ethoxyaminobutylidene)-5-(4-ethylphenyl)-cyclohexane-1,3-dione is obtained as an oil (active ingredient No. 3).
