実験手順: A solution of tert-pentylbenzene (10.04 g, 67.72 mmol) and hexamethylenetetramine (9.49 g, 67.7 mmol) in trifluoroacetic acid (100 ml) was stirred at 90° C. overnight. The reaction solution was evaporated under reduced pressure, diluted with water, alkalified with potassium carbonate, and extracted twice with ethyl acetate. The recovered organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to give a crude product of 4-(tert-pentyl)benzaldehyde as a dark brown liquid. The reaction solution was evaporated under reduced pressure diluted with water extracted twice with ethyl acetate The recovered organic layer was dried over anhydrous sodium sulfate the solvent was evaporated under reduced pressure

実験手順: 162.2 g of p-tert.amyl-benzaldehyde are added under nitrogen gasification to a solution of 1.56 g of potassium hydroxide in 113 ml of methanol and 48.8 g of propionaldehyde are subsequently added dropwise at 40° C. over a period of 6 hours. The mixture is subsequently stirred at 40° C. for an additional hour, 2 ml of acetic acid are added and the mixture is concentrated on a rotary evaporator. The oily suspension is taken up in ether, washed neutral with water, dried and evaporated. By distillation there is obtained pure 3-(p-tert.amyl-phenyl)-2-methyl-acrolein of boiling point 117°-120° C./0.035 Torr. are subsequently added dropwise at 40° C. over a period of 6 hours the mixture is concentrated on a rotary evaporator washed neutral with water dried evaporated By distillation there
