Potassium Iodide → HCID 907980, compound

Participants

Reaction Steps

10 g of 7-hydroxy-2-methyl-isoflavone, 10 g of anhydrous potassium carbonate, 1 g of potassium iodide and 12.5 g of benzyl chloride are boiled in 200 ml of anhydrous acetone for 2 hours with stirring, under a reflux condenser. On subjecting the mixture to steam distillation, the crude product precipitating from the water is filtered, dried, and recrystallized from a mixture of 100 ml of methanol and 40 ml of acetone, affording white needle crystals of 7-benzyloxy-2-methyl-isoflavone, m.p. 139°-141° C.
