Procedure

880 mg (4.59 mmol) of 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride, 0.63 ml (4.52 mmol) of triethylamine and 860 mg (4.55 mmol) of pivaloyl-L-serine were added to 1.231 g (4.50 mmol) of 4-(5H-dibenzo[a,d][7]annulen-5-ylidene)piperidine in 20 ml of dichloromethane in ice bath, and they were stirred at room temperature overnight. 1 N hydrochloric acid was added to the reaction mixture. After extracting with dichloromethane, the organic layer was dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by the silica gel chromatography (hexane:ethyl acetate=7:3 to 1:2) to obtain the title compound.
