Versuchsvorschrift

Dimethylformamide (150 ml) was added to 21.3 g of 1,9-dibromononane, 19.8 g of 4-hydroxybenzaldehyde and 21.7 g of potassium carbonate, and the mixture was stirred at 90° C. for 1.5 hours. The reaction mixture was cooled to room temperature and poured into water, and the thus formed precipitate was washed with water and then dried under a reduced pressure to obtain 26.9 g of 1,9-bis(4-formylphenoxy)nonane.
