88 g of n-heptylbenzene are taken up in 50 ml of trifluoroacetic acid and 70 g of hexamethylenetetramine. The whole is refluxed for 12 hours after which the excess of trifluoroacetic acid is distilled off by means of a water jet airpump. The mixture is then poured in ice water and neutralized with soda. After extraction with ether the resulting ether solution is evaporated and the resulting 4-heptylbenzaldehyde is used for the following process step.
