반응 단계
150 g ferric chloride in 400 ml water are added to a solution of 100 g (E)-isoeugenol in 1.3 liter 75 percent ethanol and allowed to stand for 24 hours at 0° C. The resulting sediment is filtered off and recrystallized from ethanol, resulting in 53 g trans-2,3-dihydro-2-(4-hydroxy-3-methoxyphenyl-7-methoxy3-methyl-5-(E)-propenylbenzofuran ("dehydrodiisoeugenol") as colorless crystals; melting point 132°-133° C.
