Reaction Steps

4-(2-Fluorenyl)-butan-2-one (4.72grams) was dissolvedin a mixture of 60 ml of pyridine and 5 ml of water, the mixture was heated at 60° C., and stirred. Potassium permanganate (6.8 grams) was added thereto little by little during 2 hours. When the addition was finished, the mixture was stirred for 2 hours more. The reaction solution was filtered, the filtrate was concentrated, and the resulting residue was dissolved in chlroform, the solution was washed with in the order of 10% hydrochloric acid, water, saturated sodium bicarbonate, and water, then dried with magensium sulfate, the solvent was evaporated therefrom, and the residue was recrystallized from ethanol to give 1.3 grams of 4-(9-oxo-2fluorenyl)-butan-2-one, yellow crystals, m.p. 75°-77° C.
