실험 절차

Under nitrogen, to a solution of N-benzyl-(3-isopropoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amine (258 mg) and (2S)-3-phenoxy-1,2-epoxypropane (138 mg) in dichloromethane (5 ml) was added ytterbium(III) trifluoromethanesulfonate (52 mg) at room temperature, and the mixture was stirred at the same temperature for 60 hours. The resulting mixture was poured into saturated aqueous sodium hydrogencarbonate and extracted with ethyl acetate. 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=10:1 to 5:1) to give (2S)-1-[N-benzyl-N-(3-isopropoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-amino]-3-phenoxy-2-propanol (303 mg)
