실험 절차

After diluting the solution with ether, it was washed with 50-100 ml of water, dried over magnesium sulfate and distilled. After distillation of the petroleum ether, 1,1,1-trichloro-4-methyl-4-penten-2-ol (74.9 g, 71% yield)) was obtained; bp, 106°-108°/25 mm. 1,1,1-Trichloro-4-methyl-4-penten-2-ol (74 g, 0.36 mole) was heated at 140°-150° for 18 hours. After cooling, the alcohol was diluted with ether, and the ethereal solution was treated with activated charcoal. The ether was removed by evaporation to afford crystalline 1,1,1-trichloro-4-methyl-3-penten-2-ol (43.4 g, 59% yield) after recrystallization from petroleum ether.
