Procedure
200 mg (0.545 mmol) of 2-[4-(5H-dibenzo[a,d][7]annulen-5-ylidene)-1-piperidinyl]-2-oxoethanamine hydrochloride was suspended in 2 ml of dichloromethane. 0.19 ml of triethylamine was added to the obtained suspension. A solution of 96.5 mg (0.654 mmol) of 1-piperidinecarbonyl chloride in 3 ml of dichloromethane was added dropwise to the resultant mixture under cooling with ice, and they were stirred at room temperature for 30 minutes. Dichloromethane was concentrated under reduced pressure. Ethyl acetate was added to the residue. The resultant mixture was washed with saturated aqueous sodium hydrogencarbonate solution. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by the basic silica gel chromatography (hexane:ethyl acetate=4:1 to 1:4) to obtain the title compound.
