Reaction Steps
6.3 mL (6.3 mmol, 2.7 eq) of a 1 M solution of LiAlH4 in THF were dissolved in 20 mL of THF in a 250 mL flask under argon. The reaction medium was cooled to −78° C. and 478 mg (2.3 mmol, 1 eq) of (9H-fluoren-9-yl)-acetonitrile in solution in 20 mL of THF were added dropwise. The temperature was allowed to rise progressively to ambient temperature. Stirring was continued for 5 hours, then the medium was hydrolysed at 0° C. by addition of 30 mL of a sodium and potassium tartrate solution. The THF was evaporated and the aqueous phase was extracted with ethyl acetate. After drying over MgSO4 and evaporation of the solvent, the crude product was subjected to chromatography over silica gel (elution gradient: CH2Cl2—CH2Cl2/MeOH: 9/1 to CH2Cl2/MeOH/NH4OH: 9/1/0.5). The 2-(9H-fluoren-9-yl)-ethylamine was obtained.
