実験手順

To a solution of 181 mg of the crude tert-butyl[(1R)-1-(1-naphthyl)ethyl][(3-phenylpiperidin-4-yl)methyl]carbamate and 0.114 mL of triethylamine in 3.0 mL of THF was added 171 mg of methyl 3-chloro-4-{[(4-nitrophenoxy)carbonyl]amino}benzoate at room temperature, followed by stirring overnight. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with chloroform, and the organic layer was dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 352 mg of methyl 4-({[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]carbonyl}amino)-3-chlorobenzoate as a crude product. ESI+: 656
