Procedure
173 mg (0.70 mmol) of 5H-dibenzo[a,d][7]annulen-5-ylidenacetic acid, 124 mg (0.77 mmol) of t-butyl N-(2-aminoethyl)carbamate, 143 mg (0.75 mmol) of 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride and 0.11 ml (0.79 mmol) of triethylamine were stirred in 5 ml of dichloromethane at room temperature overnight. The reaction mixture was washed with saturated aqueous sodium hydrogencarbonate solution and the organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was purified by the silica gel chromatography (hexane:ethyl acetate=7:3) to obtain the title compound.
