Reaction Steps

A mixture of (2S)-1-[N-benzyl-N-(2-chloro-3-methoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl) amino]-3-phenoxy-2-propanol (172 mg) and 10% palladium on activated carbon (50% wet, 50 mg) in a mixture of chlorobenzene (2 ml) and methanol (2 ml) was stirred at room temperature in the presence of hydrogen at an atmospheric pressure for 2 hours. After filtration, the filtrate was evaporated in vacuo. The residue was purified by column chromatography on silica gel (chloroform:methanol=20:1 to 10:1) and followed by treatment with 4N hydrogen chloride in ethyl acetate to give 1-(2-chloro-3-methoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amino-3-phenoxy-2-propanol hydrochloride (95 mg).
