実験手順

To a solution of N-(3-fluoromethoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-N-[(2S)-2-hydroxy-3-phenoxypropyl]-tert-butoxycarbonylamine (41 mg) in ethyl acetate (2 ml) was added 4N hydrogen chloride in ethyl acetate (0.45 ml) at room temperature, and the mixture was stirred at the same temperature for 5.5 hours. The mixture was poured into a mixture of saturated aqueous sodium hydrogencarbonate and ethyl acetate, followed by being made basic with saturated aqueous sodium hydrogencarbonate. After separation, the organic layer was dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (silica gel, chloroform:methanol=10:1) to give (2S)-1-(3-fluoromethoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amino-3-phenoxy-2-propanol (23 mg).
