実験手順

In a 500-mL round-bottom flask, sulfuric acid (48 mL; 30%) was added to a stirred tetrahydrofuran (150 mL) solution of 1-methoxy-3,3-dimethylhexa-1,5-diene (15.89 g, 0.113 mol). After the mixture had been stirred for 1 hour, it was gradually poured into saturated sodium bicarbonate (ca. 500 mL), and then extracted with diethyl ether (4×200 mL). The combined extracts were washed with brine, dried over sodium sulfate, and filtered. Evaporation of the solvent gave the title compound as a pale yellow liquid.
