Procedure

20.5 g (0.044 mol) of bis-(3,4-dipropyloxybenzal)acetone were dissolved in 100 ml of methanol, 1 g of palladium/carbon was added thereto, and the mixture was hydrogenated in an autoclave at 25° to 30° C. under a hydrogen gas pressure. After the palladium/carbon was filtered off, the filtrate was condensed to deposit crystals followed by filtering to obtain 15.9 g of white crystals (yield: 77%).
