Reaction Steps

Catalytic reduction of 5.05 g of the 2',3,4,4'-tetrakis(methoxymethoxy)chalcone obtained as the intermediate in Specific Example 19 was carried out by using 1.76 g of 5% palladium/carbon according to customary procedures. After the reaction, the reaction liquid was filtered and the solvent was removed from the filtrate by distillation to obtain 4.94 g (yield=97.3%) of 1-[2,4-bis(methoxymethoxy)phenyl]-3-[3,4-bis(methoxymethoxy)phenyl] -1-propanone.
