Reaction Steps

Then, 80 ml of an ethyl acetate solution of 7.22 g of 2'-hydroxy-4,4',6'-tris(methoxymethoxy)-3,3'-bis(3-methyl-2-butenyl)chalcone was added to a suspension of 1.67 g of 5% palladium/carbon in 50 ml of ethyl acetate, in which a hydrogen gas had been sufficiently absorbed in advance, and the mixture was stirred at room temperature under atmospheric pressure in a hydrogen gas atmosphere for 4 hours. After the reaction, the suspension was filtered and the solvent was removed from the filtrate by distillation to obtain 6.23 g (yield=85.3%) of 1-[2-hydroxy-4,6-bis(methoxymethoxy)-3-isopentylphenyl]-3-(3-isopentyl-4-methoxymethoxyphenyl)-1-propanone in the form of a syrup.
