Crude butyl-[1-(2-cyclopropyl-4,6-bis-trifluoromethyl-phenyl)-methylidene]-amine (intermediate AL, 3.54 g, 10.5 mmol) was dissolved in 8 mL water. Hydrochloric acid (25%, 0.49 mL) was added and the mixture was refluxed for 2 h. The mixture was extracted three times with ethyl acetate. The combined organic phases were dried on sodium sulfate, filtered and evaporated. The crude material, brown oil (1.01 g, 34%) was used without further purification.
