반응 단계
12 g of 7-hydroxy-isoflavone are boiled for 2 hours under a reflux condenser with 10 g of potassium carbonate and 9 g of isopropyl bromide in 40 ml of dimethyl formamide. On pouring the reaction mixture into water, the separated product is recrystallized from acetone, yielding 7-isopropoxy-isoflavone. In a similar way all the other isoflavone derivatives described in Example 7 can be prepared.
