실험 절차

In the same manner as in the preceeding Examples, 50 g of ethyl ortho-propionate, 21.6 g of dehydrolinalool and 2.1 g of isobutyric acid were reacted at 135° to 140°C. for 4 hours and the resulting reaction mixture was subjected to distillation under reduced pressure. Ethyl 2,5,9-trimethyl-3,4,8-decatrienoate was obtained in a yield of 98.5% from a fraction boiling at 129 to 130°C. under 2.3 mm Hg.
