실험 절차
A mixture of 12.9 g (0.15 mole) of 3-methyl-2-buten-1-ol, 48.6 g (0.3 mole) of ethyl orthoacetate and 0.5 g of hydroquinone was heated at 140° for 20 hours with stirring. Ethanol was removed by distillation during the heating. At the end of 20 hours, the mixture was distilled under reduced pressure to give, after removal of unreacted ethyl orthoacetate, 17.6 g (75% yield) of ethyl 3,3-dimethyl-4-pentenoate, b.p. 74°-78°/55 mm.
