Participants

Reaction Conditions

Reaction Steps

2.17 g of 3-fluoro-4-nitrophenol and 5 g of 2-aminofluorene were mixed and stirred for 9 hours at 140° C. The raw mixture was taken up in ethyl acetate and water and washed with 1N aqueous hydrochloric acid. The aqueous phase was extracted with ethyl acetate, and the combined organic phases were washed three times with 2N aqueous hydrochloric acid and once with saturated sodium chloride solution, dried on sodium sulfate and concentrated by evaporation in a vacuum. The residue was chromatographed on silica gel.
