Procedure
Then, a suspension of 2.52 g of 5% palladium/carbon in 50 ml of ethyl acetate was hydrogenated for 2 hours, and a solution of 5.11 g of 2',4,4'-tris(methoxymethoxy)chalcone in 50 ml of ethyl acetate was added to the suspension and hydrogenation was carried out. After the reaction, the palladium/carbon was removed by filtration and the filtrate was concentrated under a reduced pressure to obtain 1-[2,4-bis(methoxymethoxy)phenyl]-3-(4-methoxymethoxyphenyl)-1-propanone.
