Then, a suspension of 4.10 g of 5% palladium/carbon in 50 ml of ethyl acetate was saturated with hydrogen, and 60 ml of an ethyl acetate solution of 6.61 g of 2'-hydroxy-4,4',6'-tris(methoxymethoxy)chalcone was added to the suspension and hydrogenation was carried out. After the reaction, the reaction liquid was filtered and concentrated under a reduced pressure to obtain 6.10 g (yield=91.8%) of 1-[2-hydroxy-4,6-bis(methoxymethoxy)phenyl]-3-(4-methoxymethoxyphenyl)-1-propanone.
