Procedure

A mixture of (2S)-1-[N-benzyl-N-(3-chloro-6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl)amino]-3-phenoxy-2-propanol hydrochloride (121 mg) and 10% Pd/C (50% wet, 18 mg) in chlorobenzene (1.8 ml) and MeOH (0.4 ml) was stirred at room temperature in the presence of hydrogen at an atmospheric pressure for 1 hour and filtered. The filtrate was evaporated in vacuo, and the residue was partitioned between ethyl acetate and a saturated aqueous solution of sodium bicarbonate. The organic layer was separated, washed with brine, dried over sodium sulfate and evaporated in vacuo. The residue was chromatographed (dichloromethane-methanol) over silica gel (2.0 g). The eluate was treated with 4N hydrogen chloride in ethyl acetate and evaporated in vacuo. The residue was triturated in diisopropyl ether, and the precipitated powder was collected by filtration to afford (2S)-1-(3-chloro-6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl)amino-3-phenoxy-2-propanol hydrochloride (74 mg, 75%) as a colorless powder.
