実験手順
The production process (B) comprises the step (3) of reacting 1,2-methylenedioxybenzene [formula (1)], methacrolein and acetic anhydride with each other to produce 1-acetoxy-2-methyl-3-(3,4-methylenedioxyphenyl)-1-propene [formula (3)]; and the step (2) of subjecting the obtained 1-acetoxy-2-methyl-3-(3,4-methylenedioxyphenyl)-1-propene [formula (3)] to hydrolysis reaction or to transesterification reaction with an alcohol, followed by subjecting the resulting reaction mixture to distillative purification.
