Versuchsvorschrift

A mixture of 1.00 g of p-hydroxybenzaldehyde, 1.46 g of isoamyl iodide and 1.80 g of potassium carbonate in 15 ml of N,N-dimethylformamide was stirred at room temperature for 2 days. Water was added to the reaction mixture, and the product was extracted with ethyl acetate. The ethyl acetate layer was washed in sequence with 1N sodium hydroxide, water and saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give 1.34 g of p-(3-methylbutoxy)benzaldehyde.
