Reaction Steps
A suspension of powdered iron (160 mg) and ammonium chloride (15 mg) in a mixture of ethanol (6 ml) and water (2 ml) was refluxed, and to this one was dropwise added (2S)-1-[N-benzyl-N-(3-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amino]-3-phenoxy-2-propanol (158 mg) in ethanol (3 ml). After being further refluxed for 1 hour, insoluble materials were filtered off. The filtrate was evaporated in vacuo. The residue was dissolved into a mixture of saturated aqueous sodium hydrogencarbonate and ethyl acetate. After separation, the organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=2:1 to 1:1) to give (2S)-1-[N-(3-amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-N-benzylamino]-3-phenoxy-2-propanol (122 mg).
