Procedure

5 ml of 4 N hydrochloric acid/1,4-dioxane solution was added to 184.1 mg (0.357 mmol) of t-butyl 3-[4-(5H-dibenzo[a,d][7]annulen-5-ylidene)-1-piperidinyl]-3-oxopropyl(neopentyl)carbamate, and they were stirred for 1 hour. The solvent was evaporated under reduced pressure. 5 ml of diethyl ether was added to the residue, and then 1 ml of 4 N hydrochloric acid/ethyl acetate solution was added thereto. The precipitates thus formed were taken by the filtration, washed with diethyl ether and dried under reduced pressure to obtain the title compound.
