Reaction Steps

Then an ethyl acetate solution of 21.1 g of 2'-hydroxy-4,4',6'-tris(methoxymethoxy)-3'-(2-propenyl)chalcone was added to a suspension of 8.0 g of 5% palladium/carbon in 50 ml of ethyl acetate, in which a hydrogen gas had been sufficiently absorbed, and the mixture was stirred at room temperature in a hydrogen atmosphere for 3 hours. After the reaction, the reaction mixture was filtered and the solvent was removed from the filtrate by distillation to obtain quantitatively 21.2 g of 1-[2-hydroxy-4,6-bis(methoxymethoxy)-3-n-propylphenyl]-3-(4-methoxymethoxyphenyl)-1-propanone in the form of a colorless oil.
