실험 절차

A mixture of 65.6 g of ethyl ortho-acetate, 30.4 g of dehydrolinalool and 1.5 g of isobutyric acid was reacted at 130° to 140°C. for 8 hours. Distillation was conducted after the reaction in the same manner as in the preceeding Examples, and a fraction boiling at 92 to 94°C. under 0.5 mm Hg was collected. Ethyl 5,9-dimethyl-3,4,8-decatrienoate was obtained in a yield of 96%.
