Reaction Steps

Then, 13.05 g of the so-obtained 2'-hydroxy-4,4',6'-trimethoxy-3'-(3-methyl-2-butenyl)chalcone was catalytically reduced by using 410 ml of ethyl acetate and 4.0 g of 5% palladium/carbon according to customary procedures, and after the reaction was conducted for 3 hours, the reaction liquid mixture was filtered, and the solvent was removed from the filtrate by distillation. The obtained residue was recrystallized from methanol to obtain 12.45 g (yield=94.11%) of 1-(2-hydroxy-4,6-dimethoxy-3-isopentylphenyl)-3-(4-methoxyphenyl)-1-propanone in the form of a light-yellow needle.
