実験手順

Piperonyl alcohol (10 g, 65.7 mmol) was dissolved in benzene. Triethylamine (11 ml, 78.8 mmol) and thionyl chloride (11 ml, 131.4 mmol) were added dropwise thereto and was stirred for 24 hours at 0° C. The reaction mixture was extracted with sodium bicarbonate and ethyl acetate, the organic layer was separated, and dried over anhydrous magnesium sulfate to obtain 5-chloromethyl benzo[1,3]dioxol (11.2 g, yield 100%).
