실험 절차

A solution of 6.7 g. of 9-(3-aminopropyl)-9-aminocarbonylfluorene (prepared as described in Example 29) in 90 ml. of ethanol containing 1.6 g. of acetone was stirred at 40° C. for sixteen hours. The reaction mixture was then hydrogenated for two hours at ambient temperature in the presence of 2.0 g. of 5% palladium on carbon and hydrogen at a pressure of 60 psi. The reaction mixture next was filtered and the solvent was removed from the filtrate by evaporation to provide a foam. The foam was dissolved in ethyl acetate and then extracted into 1 N hydrochloric acid. The aqueous acid layer was separated, make alkaline with 50% sodium hydroxide, and the product was extracted into fresh ethyl acetate. The organic extracts were combined, washed with water, dried, and the solvent was removed by evaporation under reduced pressure to provide 9-(3-isopropylaminopropyl)-9-aminocarbonylfluorene identical to that obtained in Example 27.
