Reaction Steps

To a solution of 9-formyl-9,10-dihydro-9,10-methanoanthracene (3.5 g) in acetone (17 ml) was dropwise added Jones' reagent (5.0 ml) at room temperature. The reaction mixture was stirred at room temperature for 1 hour, diluted with water and extracted with ethyl acetate. The ethyl acetate extract was washed with water, dried over anhydrous sodium sulfate and evaporated to dryness to give 9,10-dihydro-9,10-methanoanthracene-9-carboxylic acid. M.P. 199.5°-200.5° C.
