Reaction Steps

To 350 ml of ethyl acetate were added 17 grams of 4-(2-fluorenyl)-3-buten-2-one and 2 grams of 10% palladium carbon powder, the mixture was warmed at 40°-50° C., and hydrogen was introduced in under ordinary pressure. When the absorption of hydrogen ceased, the catalyst was removed by filtration, the filtrate was concentrated, and ethyl acetate was removed therefrom. Crystals separated out therefrom were recrystallized from methanol to give 9.65 grams of 4-(2-fluorenyl)-butan-2-one, white crystals, m.p. 99°-101° C.
