실험 절차

To a suspension of 5.000 g of methyl 3-hydroxybenzoate, 6.955 g of 4-nitrophenyl chloroformate, and 100 mL of toluene was added 4.81 mL of triethylamine at room temperature, followed by stirring overnight. The insolubles were removed by filtration, and as solvent was removed by distillation under reduced pressure to obtain 5.948 g of methyl 3-{[(4-nitrophenoxy)carbonyl]oxy}benzoate as a pale yellow solid. To a mixture of 100 mg of methyl 3-{[(4-nitrophenoxy)carbonyl]oxy}benzoate, 139 mg of tert-butyl {[3-(3-fluorophenyl)piperidin-4-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate, and 4 ml of THF was added 0.084 mL of triethylamine at room temperature, followed by stirring overnight. A saturated aqueous sodium hydrogen carbonate solution was added thereto, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 196 mg of 3-(methoxycarbonyl)phenyl 4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidine-1-carboxylate as a pale yellow oily compound.
