Under nitrogen, to a solution of N-(3-fluoromethoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-N-tert-butoxycarbonyl-[(2S)-3-phenoxy-2-(triethylsilyloxy)propyl]-amine (300 mg) in tetrahydrofuran (5 ml) was added tetra-n-butylammonium fluoride (1M in tetrahydrofuran, 0.58 ml) at 5° C., and the mixture was stirred at the same temperature for 15 minutes. The resulting mixture was poured into water 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=3:1) to give N-(3-fluoromethoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-N-tert-butoxycarbonyl-[(2S)-2-hydroxy-3-phenoxypropyl]amine (227 mg).
