Versuchsvorschrift

Ethyl (2E,4E)-dodeca-2,4-dienoate (11.84 g) was dissolved in methanol (130 ml) and 2M aqueous sodium hydroxide solution (35 ml) was added. The reaction mixture was heated to 60° C. until full conversion was observed. After cooling down to room temperature the mixture was acidified with diluted aqueous HCl. The reaction mixture was extracted with ethyl acetate and the organic layer was washed with brine, dried over sodium sulfate, and solvents were evaporated. The crude product was used for the next step without further purification.
