3-(9-Fluorenyl)propionic acid was prepared from 2-(9-fluorenyl) ethyl-1,3-dioxolane (50.0 g, 187 mmol) which was dissolved in 20 ml of acetone and 450 ml of Jones' reagent (64 g chromic acid and 64 ml of sulfuric acid in 400 ml of water). After the reaction was complete, the acetone was evaporated, the residue taken into ethyl acetate, washed with water, and organic layer extracted with 1N sodium hydroxide which was acidified with 10% HCl to yield a tan precipitate.
