Reaction Steps
1.7 g sodium is allowed to react with 150 ml absolute ethanol. After complete disappearance of sodium, one adds 13.5 g 4-chloro-3-formyl-flav-3-ene. After stirring 30 minutes at 40° C., 300 ml of water is added and a precipitate is formed, filtered, washed with water and dried. The solid is crystallized in hexane. Pure 4-ethoxy-3-formyl-flav-3-ene is obtained as yellow crystals; m.p. 80°-82° C.
