To a reflux apparatus add with stirring add 18.4 g of dibromochalcone and 16.5 mL of methanol, to this solution rapidly add a solution made from 2.3 g of sodium and 23 mL of methanol, reflux for 1h. After the reflux, acidify the mixture with some HCl and reflux again for 5 minutes, pour the mixture to 160 mL of ice, filter and wash with 50 mL of cold methanol. Recrystallize the crude product from hot methanol.
